High-quality Cisco Compatible GLC-LH-SM

The Cisco GLC-LH-SM optical transceiver, as one type of SFP transceivers, presents a huge change in the ease of incorporating fiber optic technology into enterprise networking. SFP transceiver does not need to be configured to begin function, and offers internal calibration to optimize data throughput. And, being hot swappable, it can be assured that other network components would keep online during the replacement of the SFP transceivers. Cisco GLC-LH-SM is 1000BASE-LX/LH SFP, which is widely used in optical network systems. High-quality Cisco Compatible GLC-LH-SM is offered only $7 at Fiberstore. Here is what you need to know about Cisco GLC-LH-SM.

Features of GLC-LH-SM

Cisco GLC-LH-SM is the 1000BASE-LX/LH SFP compatible with the IEEE 802.3z 1000BASE-LX standard. Unlike other Cisco SFP transceivers that can operate either on single mode or multimode fibers, GLC-LH-SM can support on standard single mode fiber-optic with a link span of up to 10 km and up to 550 m on any multimode fibers. This industry-standard Cisco Small Form-Factor Pluggable (SFP) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network.


The GLC-LH-SM, can be used and interchanged on a wide variety of Cisco products and can be mixed in combinations of 1000BASE-SX, 1000BASE-LX/LH, or 1000BASE-ZX on a port-to-port basis Cisco Catalyst 6500 or 7600 Series Supervisor Engine 720.

Advantages of Cisco GLC-LH-SM Optics

Generally speaking, widespread adoption of fiber optic networking has been extremely high precision demands and delicate construction that came along with the media; but fiber optic cables made of glass-like material can easily damage. Also, the interfaces on either end of the cable have often been required to be very expensive, highly complex transceivers that required a large amount of intricate configuration to perform optimally, which becomes the main obstacle of the widespread adoption of fiber optic networking.

However, with Cisco GLC-LH-SM fiber optic transceivers, the challenges are a thing of the past. Here are three ways that the GLC-LH-SM transceivers make fiber optic networking very possible.

1. There is no need for Cisco SFP transceivers to configuring before function, and it also offers internal calibration to optimize data throughput.

2.  Another unique advantage of fiber optics is that these SFP transceivers are truly hot swappable, which means a transceiver failure can be solved by simply replacing a new one, then you network is back online and ready to go.

3. GLC-LH-SM fiber optics also has a single or multimode operations. Single mode allows data transmission over distances exceeding 10km, useful for very large research facilities, hospitals, or university campuses. And multimode fibers open the data floodgates, giving you maximum throughput upwards of 1.25 Gbps so that this transceiver can meet your needs whether a network solution that covers a long distance, or the huge bandwidth fiber optic.
