How to Understand PoE and PoE+ Switches

Power-over-Ethernet (PoE) is the technology that allows network switches to transmit power and data through an Ethernet cable at the same time. PoE switch streamlines both of the processes of powering and providing data to the device, which makes it a straightforward and reliable device for home network and small enterprise application. This article describes two types of PoE (PoE and PoE+) that are commonly used and provides information on what types of PoE can be used according to different applications.

PoE Versus non-PoE Technology

Power over Ethernet technology facilitates powering a device (such as an IP phone, IP Surveillance Camera, or NVR recorder) over the same Ethernet cable as the data traffic. Figure 1 shows an Ethernet Network with IP camera, PoE Switch, NVR recorder and Wireless router. Compared to non-PoE devices, PoE devices feature with flexibility that allow you to easily place endpoints anywhere in the business, even places where it might be difficult to run a power outlet.

Wireless Home Network with POE switch

PoE Versus PoE+ Technology

PoE was first defined in the IEEE 802.3af standard. PoE devices utilize PoE standard, which can provide up to 15.4W of DC power to each port. A later standard, IEEE 802.3at, known as PoE+, increases the amount of power to 30 W. The major difference between 802.3af (PoE) and 802.3at (PoE+) is that PoE+ PSEs can provide almost twice as much power over a single Ethernet cable.

PoE and PoE+

Can PoE+ devices work over PoE Ports, Or vice versa? The PoE+ standard provides support for legacy PoE devices, meaning that an IEEE 802.3af powered device (PD) can operate normally when connected to IEEE 802.3at (PoE+) power sourcing equipment (PSE). PoE+ PSEs can supply power to both PoE and PoE+ PDs. However, as PoE+ PDs require more power than PoE PSEs can provide, PoE PSEs can only supply power to PoE PDs.

PoE Switch Or PoE+ Switch

Whether to use PoE or PoE+ switch for your network, you need to calculate your required power budget carefully for all of the PDs you plan to connect. PoE+ IEEE 802.3at devices can supply a maximum of 30 watts per port, while PoE IEEE 802.3af devices can supply a maximum of 15.4 watts per port. However, some power is always lost over the length of the cable, and more power is lost over longer cable runs. The minimum guaranteed power available at the PD is 12.95 watts per port for PoE and 25.5 watts per port for PoE+.

For most endpoints, 802.3af is sufficient but there are devices, such as Video phones or Access Points with multiple radios, which have higher power needs. It’s important to point out that there are other PoE standards currently being developed that will deliver even high levels of power for future applications. Optical switches have a power budget set aside for running the switch itself, and also an amount of power dedicated for PoE endpoints.

What Are OM1, OM2, OM3 and OM4 Fiber Patch Cable?

Fiber optic cable can be divided into several types. Usually we see single-mode and multimode fiber types available on the market. Multimode fibers are described by their core and cladding diameters. The diameter of the multi-mode fiber is either 50/125 µm or 62.5/125 µm. At present, there are four commonly used OM (multimode) fibers: OM1, OM2, OM3 and OM4. Each type of them has different characteristics.

OM1 OM2 OM3 OM4 OM5 fiber cables

The picture above shows the development of OM multimode fibers. The Lime Green OM5 fibers are newly released and sure to be the mainstream transmission media in the near future. For more information about OM5 fibers, please turn to: OM5 Fiber Cable – Is It Worthwhile for 40G/100G SWDM4 Cabling Solution

OM Multimode Fiber Standard

Each “OM” has a minimum Modal Bandwidth (MBW) requirement. OM1, OM2, and OM3 are determined by the ISO 11801 standard, which is based on the modal bandwidth of the multi-mode fiber. In August of 2009, TIA/EIA approved and released 492AAAD, which defines the performance criteria for OM4. While they developed the original “OM” designations, IEC has not yet released an approved equivalent standard that will eventually be documented as fiber type A1a.3 in IEC 60793-2-10.

OM1, OM2, OM3 and OM4 multi-mode fiber

According to the above table,

  • OM1 cable typically comes with an orange jacket and has a core size of 62.5 micrometers (µm). It can support 10 Gigabit Ethernet at lengths up 33 meters. It is most commonly used for 100 Megabit Ethernet applications
  • OM2 also has a suggested jacket color of orange. Its core size is 50µm instead of 62.5µm. It supports 10 Gigabit Ethernet at lengths up to 82 meters but is more commonly used for 1 Gigabit Ethernet applications.
  • OM3 has a suggested jacket color of aqua. Like OM2, its core size is 50µm. OM3 supports 10 Gigabit Ethernet at lengths up to 300 meters. Besides OM3 is able to support 40 Gigabit and 100 Gigabit Ethernet up to 100 meters. 10 Gigabit Ethernet is its most common use.
  • OM4 also has a suggested jacket color of aqua. It is a further improvement to OM3. It also uses a 50µm core but it supports 10 Gigabit Ethernet at lengths up 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters.

OM1 Vs. OM2 Vs. OM3 Vs. OM4 Fiber

There are several differences between four kinds of multi-mode fiber, and we can see them clearly from the table below:

OM1, OM2, OM3 and OM4 multi-mode fiber

  • Diameter: The core diameter of OM1 is 62.5 µm , however, core diameter of the OM2, OM3 and OM4 is 50 µm.
  • Jacket Color: OM1 and OM2 MMF are generally defined by an orange jacket. OM3 and OM4 are usually defined with an aqua jacket.
  • Optical Source: OM1 and OM2 commonly use LED light source. However, OM3 and OM4 usually use 850 nm VCSELs.
  • Bandwidth: At 850 nm the minimal modal bandwidth of OM1 is 200MHz*km, of OM2 is 500MHz*km, of OM3 is 2000MHz*km, of OM4 is 4700MHz*km.

Why Are OM3 & OM4 Fiber Superior to OM1 & OM2?

10G OM3Both OM1 and OM2 work with LED based equipment that can send hundreds of modes of light down the cable, while OM3 and OM4 fiber are optimized for laser (eg. VCSEL) based equipment that uses fewer modes of light. LEDs can not be turned on/off fast enough to support higher bandwidth applications, while VCSELs are capable of modulation over 10 Gbit/s and are used in many high speed networks. For this reason, OM3 and OM4 are the multimode fibers included in the 40G and 100G Ethernet standard. Now OM1 and OM2 are usually used for 1G which are not suitable for today’s higher-speed networks. OM3 and OM4 are used for 10G mostly at present. But in the future, since OM3 and OM4 can support the 40G and 100G, which may make them the tendency.

400G CFP8 PAM4 & 400GBASE-SR16 NRZ Transceiver Modules

With the price of 100G QSFP28 optics and CFP form factors (CFP module/CFP2/CFP4) dropping down in 2017, 100G technology is becoming more and more popular among data center managers and IT pros in order to cope with the ever-lasting bandwidth needs. However, 100G is not the finish line. CFP multimode source agreement (MSA) demonstrated CFP8 (16X 25 Gb/s) form factor for 400 Gigabit Ethernet at OFC 2017. Although CFP8 module is still in development, it is assured to be popular in the near future. Therefore, this article will have a clearer introduction to 400G CFP8 PAM4 and NRZ modules, and compare with the former CFP modules and 400G CDFP.

100G CFP to 400G CFP8

Introduction to 400GbE CFP8 Modules

CFP8 module is the latest developing CFP from factor version, which supports eight times and four times the bandwidth density of CFP and CFP2 form factors, respectively. The CFP8 interface supports up to 16 different lanes in each direction with nominal signaling rates of 25Gb/s or 26Gb/s per lane, and either NRZ or PAM4 signaling. As the above image shows, CFP8 is approximately the size of a CFP2 optics. This interface has been generally specified to allow for 16 x 25 Gb/s and 8 x 50 Gb/s mode.

CFP8 functional diagram

Example IEEE specifications supported by CFP8:

  • 400GBASE-SR16 parallel MMF (16x25G NRZ)
  • 400GBASE-FR8/LR8 duplex SMF (8x50G PAM4 WDM)
  • 400GBASE-DR4 parallel SMF (4x100G PAM4)
  • CDAUI-16, CDAUI-8

400G CFP8 FR8 and LR8 Transceivers with PAM4 Technology

CFP8 PAM4 optics, compliant with IEEE 802.3bs 400GBASE-FR8 & LR8 electrical interface specifications, offers higher receiver bandwidth capacity for reach up to 2km and 10km. The 400GBASE-FR8 & LR8 consumes less than half the power per GB compared to a 100G CFP4 msa solution. CFP8 optics uses LC duplex fiber cables.

PAM4 and NRZ

The PAM4 stands for pulse amplitude modulation with four levels. Instead of driving the laser to generate one of the two output amplitudes, like NRZ, PAM4 technology generates four different amplitude levels, meaning a network based on PAM-4 can send twice as much data as an NRZ version.

CFP8 400GBASE-SR16 with NRZ Technology

CFP8 400GBASE-SR16 modules focus on non-return to zero (NRZ) signal modulation Scheme. To use an analogy, it means you’re sending signals in the most simple format: “light on” and “light off.” A ‘1” is transmitted as pulse of light whereas ‘0” is no light output. Based on the currently available fast VCSEL light sources only achieving data rates of 25G, sixteen channels must transmit in parallel to create a 400G data stream.

Due to the design simplicity NRZ, the modulation format of choice for all data rates up to 25Gb/s. 400GBASE-SR16 CFP8 transceivers requires 16 fiber pairs to support a total of 400Gb/s with MPO multimode cables.

What’s New With CFP8 Module?

A CFP8 module is a hot pluggable module. Compared with the former modules, the control and status reporting functions between a host and a CFP8 module use non-data control and status reporting pins on the 124-pin connector. There are three Hardware Control pins, two Hardware Alarm pins, and four pins dedicated to the MDIO interface.

Compared to CFP2/CFP4 MSA Optics

CFP8 is the proposed CFP8 from factor by MSA member companies. It maintains the large size of CFP form factor (nearly the size of CFP2, larger than CFP4 MSA modules), but supports 4x100G i.e. 4x the CFP2. Besides this, CFP8 uses less power than the former CFP form factor modules. There are 400GBASE-SR16 for parallel MMF 16x25G NRZ, and 400GBase-FR8/LR8 duplex SMF 8x50G PAM4 WDM.

CFP8 Vs. CDFP

CFP8 is not the first released 16x25G= 400G modules, but CDFP. 400G CDFP module (CD=400 in Latin), is the four generation CFP form factor. Providing a high level of integration, performance and long-term reliability, the CDFP 400 Gbps interface is available in short- and long-body versions. The specifications are compatible for use with direct attach cables, active optical cables, and connectorized optical modules. The CDFP module will support:

  • 5 meter direct attach cables
  • 100 meter multimode fiber
  • 500 meter parallel single‐mode fiber
  • 2 kilometers of duplex single‐mode fiber

The compact modules are well suited for low power applications using copper, VCSEL or silicon photonics based technology. They also targeted InfiniBand EDR hydra cables and 128GFC applications but so far little market segment pick up. Though relatively new with 2014 and 2015 rev releases, CDFP may be short lived due to the smaller more efficient developing set of CFP8 solutions.

Latest Trend With 400 Gb/s in the Industry

While 400 GbE standard is still a few years away, the need for 400 Gb/s interfaces is here today. The CDFP form factor is already being used in proprietary interfaces to interconnect high performance servers and will soon be used to interconnect switch and router chassis. 400G CFP8 FR8/LR8 PAM4 and 400GBASE-SR16 modules had been displayed at OFC 2017. Finisar, Fujitsu, and oclaro, etc MSA member enterprises will introduce low profile 400G modules in a short period.

These proprietary chassis interconnects have always been massively parallel and will continue because they provide the massive bandwidth needed to interconnect equipment so that multiple chassis perform as one big chassis. While 16 lanes is a fairly wide interface, multiple applications need the maximum amount of bandwidth that can only be provided by many parallel lanes running at the fastest speed available. It seem that CFP8 with the same 16 MPO connectors has much potential than CDFP modules. FS.COM offers a large stock MSA-compliant optical transceivers, including 100G CFP/CFP2/CFP4 MSA, CXP, and QSFP28 transceiver modules. We will keep in path with the informative world, and provide the best services & telecom products to all of our customers.

Introduction to Semiconductor Optical Amplifier (SOA)

Optical amplifier, with the introduction in 1990s, conquered the regenerator technology and opened doors to the WDM technology. It is mainly used to amplify an optical signal directly, without the need to first convert it to an electrical signal. There are many types of optical amplifiers, namely Raman amplifiers, erbium doped-fiber amplifiers (EDFAs), and semiconductor optical amplifier (SOA). This article will make a clearer introduction to SOA amplifier, and analyze its advantages and disadvantages.

transport network system

The Basics of Semiconductor Optical Amplifier (SOA)

SOA optical amplifiers use the semiconductor as the gain medium, which are designed to be used in general applications to increase optical launch power to compensate for loss of other optical devices. Semiconductor optical amplifiers are often adopted in telecommunication systems in the form of fiber-pigtailed components, operating at signal wavelengths between 0.85 µm and 1.6 µm and generating gains of up to 30 dB. Semiconductor optical amplifier, available in 1310nm, 1400nm, 1500nm, 1600nm wavelength, can be used with singlemode or polarization maintaining fiber input/output.

Key Points of SOA Amplifier

  • 1310 nm, 1400 nm, 1550 nm and 1610 nm wavelength selectable
  • High fiber-to-fiber gain of 20 dB
  • Up to 16 dBm output
  • 1 MHz with 10 ns pulse width (optional)
  • PM Panda fiber input/output (optional)
  • Similar to lasers, but with non-reflecting ends and broad wavelength emission
  • Incoming optical signal stimulates emission of light at its own wavelength
  • Process continues through cavity to amplify signal

Working principle of SOA amplifier

The basic working principle of a SOA is the same as a semiconductor laser but without feedback. SOAs amplify incident light through simulated emission. When the light traveling through the active region, it causes these electrons to lose energy in the form of photons and get back to the ground state. Those stimulated photons have the same wavelength as the optical signal, thus amplifying the optical signal.

working principle of SOA
SOA Over EFDA in DWDM Networks

As the solution below, 120km Metro Networks by Using an SOA amplifier. You may wonder why not use EDFA in the above networks.

SOA amplifier

Theoretically, SOA optical amplifiers are not comparable with EDFA in the terms of performance. The noise figure of SOA optical amplifier is typically higher, the gain bandwidth can be similar, SOAs exhibit much stronger nonlinear distortions in the form of self-phase modulation and four-wave mixing. Yet, the semiconductor optical amplifier is of small size and electrical pumped, which is often less expensive than EDFA. Additionally, SOA can be run with a low power laser.

How to Choose SOA Optical Amplifier?

When selecting SOA amplifier, you have to check the every detailed parameter in the product data sheet. But, seriously, do you understand it? No, please read the following part.

The key parameters used to characterize a SOA amplifier are gain, gain bandwidth, saturation output power and noise.

Gain is the factor by which the input signal is amplified and is measured as the ratio of output power to input power (in dB). A higher gain results in higher output optical signal.

Gain bandwidth defines the range of bandwidth where the amplification functions. A wide gain bandwidth is desirable to amplify a wide range of signal wavelengths.

Saturation output power is the maximum output power attainable after amplification beyond which no amplification is reached. It is important that the SOA has a high power saturation level to remain in the linear working region and to have higher dynamic range.

Noise defines the undesired signal within the signal bandwidth which arises due to physical processing in the amplifier. A parameter called noise figure is used to measure the impact of noise which is typically around 5dB.

Conclusion

SOA amplifier is the economic, high-performance solution for long-hual WDM networks. SOA amplifier, due to its features, can be used in Booster and in-line amplification, optical network, general purpose test and measurement and fiber sensing. However, it also has its limit. In semiconductor optical amplifiers, electron-hole recombination occurs which will affect the performance of the whole line. FS offers EDFA, SOA, Raman optical amplifiers of excellent quality and price. For more detailed information, please feel free to contact us.

OM5 Fiber Cable – Is It Worthwhile for 40G/100G SWDM4 Cabling Solution

OM5 multimode fiber, as the advanced version of the old OM4 fiber, is thought to be the future of multimode cabling. It is the Wideband multimode fiber (WBMMF) that can support wavelengths between 850nm and 953nm. It is also designed to support the short wavelength division multiplexing (SWDM)—one of the new technology for 40G/100G connection. However, will it be the ideal transmission medium for 40GbE/100GbE cabling solution?

How OM5 Fiber Developed

Over the past thirty years, multimode fiber has been evolved from OM1 to OM5 multimode fiber. OM1 and OM2 fiber, released at the end of 20th century, are the legacy 125µm multimode fiber that are working fine in 10Mb/s, 100Mb/s and 1000Mb/s cabling solution. However, with the high speed data rate like 10Gb/s, 40Gb/s, 100Gb/s and beyond coming into our life, multimode cabling (OM1 and OM2 ) with LEDs can not meet the requirement. The laser-optimized OM3 and OM4 has been developed subsequently. OM4 fiber cable, with the internal construction, possess higher modal bandwidth than OM3 fiber, which is commonly used fiber medium for 40G/100G connection.

OM1-OM5 fiber

But there is a problem. In a 40G layout, fiber optic technicians have to use one MTP fiber and 4 OM4 duplex fibers (total 8 fibers), which is obvious not preferable for high-density cabling networks. So here comes the OM5 fiber. By utilizing SWDM technology, it can greatly reduce fiber count into 2 fibers (4×10G) in 40G networks, 2 fibers (4×25G) in 100G links. OM5 is the lime green multimode fiber, displayed as follows.

OM5 Fiber

OM5 Fiber for 40G/100G SWDM4 Cabling Solution

Reduce fiber count for 40G/100G connection—OM5 fiber as the advanced version of OM3/OM4 fiber, is backward compatible with OM3 and OM4 fiber cabling. And with the SWDM technology, this fiber can only use two OM5 fibers and 40/100G SWDM4 transceivers in 40G and 100G SWDM4 cabling.

Longer-transmission distance—OM5 is designed and specified to support at least four WDM channels at a minimum speed of 28Gbps per channel through the 850-953 window. Compared to OM4 fiber cable, it is specified only to work at the 850 nm window. OM5 multimode fiber delivers higher value to network owners for distances up to 440m (for data rates up to 40Gbps), and allows for smooth migration to 400Gbps for distances up to 150m. While OM4 fiber cover the distance of 350m, 100m over 40G/100G respectively.

Easy management & installation—in 40G/100G network, multimode connectivity together with MTP/MPO systems makes for a more user-friendly solution for data centers as well as building and campus backbones, especially in cable installation, troubleshooting, cleaning, and overall maintenance.

FS OM5 Cable Solution

FS offer Lime green OM5 fibers. All our OM5 fiber cables are guaranteed by End Face Geometry Test, Continuity Test, and 3D interferometry Test to be high quality. Available in LC, SC, FC, ST, etc. Connectors, and the cable length of OM5 fiber can be provided from less than 1 meter to more than 100 meters, which will well meet the needs for 400m transmission of 40G SWDM4 QSFP+ module and 100m transmission of 100G SWDM4 QSFP28 module, as well as the links on the same rack or row.

      • You can feed a good size office off of 2 of the Long-Range APs. the controller will handle the overlap for you.

How to Make a Choice Between Ubiquiti and Cisco Switches?

Cost: Price is the biggest incentive in most of the case. A general quote for ubiquiti and Cisco, the Cisco is typically 3 times the cost of ubiquiti. Considering the cost differences between Unifi and Cisco catalyst switches, what makes Cisco so pricey. According to many fiber optic technicians, the ubiquiti system will give them 99% uptime while the Cisco system will give them 99.99% uptime.

Performance: Except the budget, another thing to add into the account is going to be bugs in the code/hardware failures. Within the telecommunication industry, you are not going to find much better, as far as stability is concerned, than Cisco.

Support: With Cisco, you will get some of the best support in the industry. Ubiquiti Unifi switches are quite easy to install and manage. Their controllers are software based, which are quite easy to work with.

Together, If your require a more secure, more robust solution to meet your enterprise and complexity needs, then Cisco is your best option. If you are small to medium sized company and are not trying to create a holo projection of the wheel at every desk. Ubiquiti will be a great fit and should more than meet your needs.

Mikrotik Vs Ubiquiti – Which One is Better for Home Network?

Ubiquiti Networks and Mikrotik were the rising stars in telecom field for the past year and a half, I have heard various fiber optic technicians telling me that Ubiquiti is better suited wireless applications while Mikrotik is excellent at what it does best—routers. As the cheap and reliable alternative to Cisco expensive equipment, Mikrotik has a learning curve not many can endure and Uniquiti, famous for its 1G/10G Unifi Switches, also has its limits. So, how to make a choice between them? This article will offer detailed information about Ubiquiti and Mikrotik in terms of target markets, price point as well as their pros and cons, from the perspective of a long-time Ubiquiti and Mikrotik user.

Mikrotik Vs Ubiquiti

Target Markets

After looking around at their website, You must admit the Ubiquiti website is a bit better than the Mikrotik site. But, there is no way to say witch one is better? Each of them are making some unique products.

Founded in 1996, MikroTik is a Latvian company aimed to develop routers and wireless ISP systems. Mikrotik offers a complete solution for wireless connectivity needs from the mANTBox, SXT, LHG, DynaDish to hAP AC. And they are also famous for their router devices. Mikrotik even launch the Mikrotik academy by expanding RouterOS learning possibilities for educational institutions.

While Ubiquiti Networks is offering Unifi series devices and its wireless accessories. UBNT has Unifi series, setting up WIFI network could not be easier, range and performance is superior. For detailed information about Unifi switches and its compatible optical transceivers, please see this article.

All in all, in noisy environment, UBNT is more stable and reliable due to its good antenna design, where Mikrotik devices are reconnecting constantly. Mikrotik have CCR routers, they are performing great, there was DDoS attack targeted to my customers network, CCR12G CPU where running at 80%, but did not crashed.

Unifi Switches Or Mirotik Routers

UBNT Unifi Switches and Mirotik Routers are the hot selling products. Both of the two hardware providers are widely deployed in WISP networks, and their switches and routers are software based which are 1/10 or less of the cost of the equivalent Cisco/Juniper products.

Ubiquiti offers an amazing price for wired speed switching, especially their Edgeswitch, Unifi switches, and Edgerouter. Their Edgerouter solutions seem to be faster than Mikrotiks solutions. UBNT are no longer providing the Edgeswitch series switches.

US-8 Managed Gigabit Switches

Ubiquiti UniFi Switch is available with either 8, 16, 24 or 48 RJ45 Gigabit ports at either 250 or 750 watts. The UniFi Switch delivers robust performance, PoE+ support, and intelligent switching for growing networks. The UniFi switch targets the Enterprise / SMB market, which is designed for a wider IT audience, and therefore, tend to be simpler, and easier to use. For its total, non-blocking throughput, the 24port model supports up to 26 Gbps, while the 48-port model supports up to 70 Gbps. The above image shows the US-8 8-port managed Gigabit switches with PoE Passthrough.

  • Mirotik Routers

Mikrotik also makes routers and switches and supports advanced features such as MPLS. Ubiquiti routers use Cavium chips so they are not 100% software solutions, having a bit of programmable hardware support. Although most Mikrotik products are 100% software-based, their flagship router nowadays, CCR, also has similar hardware acceleration from Tilera.

CCR1016 is an industrial grade router with a cutting edge 16 core Tilera CPU. The CCR1016-12S-1S+ seen in the below image, comes with redundant power supplies and one RJ45 SFP 10/100/1000M copper module. It has 12 SFP Ports and one SFP+ port for 10G connectivity.

Mikrotik-Cloud-Core-Router

Wireless and BRAS-type solutions under RouterOS work fine, but routing has been a challenge since they moved from Quagga to XORP due to licensing issues; Mikrotik uses a lot of open source but published very little code, drawing extensive criticism from the open-source community. Although it’s unknown to me if they are still using XORP, whatever they use still has flaws.
