The industry-standard Cisco Small Form-Factor Pluggable (SFP) Gigabit Interface Converter links your switches and routers to the network. The hot-swappable input/output device plugs into a Gigabit Ethernet port or slot. Optical and copper models can be used on a wide variety of Cisco products and intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-EX, 1000BASE-ZX, or 1000BASE-BX10-D/U on a port-by-port basis.

Features and benefits

Hot swappable to maximize uptime and simplify serviceability
Flexibility of media and interface choice on a port-by-port basis, so you can “pay as you populate”
Robust design for enhanced reliability
Supports Digital Optical Monitoring (DOM) capability

1000BASE-LX/LH SFP for both multimode and single-mode fibers

The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable.

You can't go wrong with these. 10km on single-mode, no sweat. The DOM actually works, which is nice for troubleshooting fiber runs. Standard Cisco quality—plug it in and forget about it. 5

Standard Cisco 1G LX/LH optics. Does 10km no sweat. The DOM feature actually works, which is nice for troubleshooting. Nothing fancy, just works every time. 5

Works great, just what I needed for AT&T fiber to new core switch. 5

Wolfgang Lins	02/24/2025 EST
funktoniert problemlos in Cisco 3850 Switches mit SFP Fibres. Fragt sich nur woher die Ware stammt - oder anders herum warum es bei Cisco Distribution 5x soviel kostet.... 5

Kelenna	12/16/2024 EST
This GLC Module can spans of up to 10 km and up to 550 m,1000BASE-LX/LH SFP is very good. I have bought two items from this seller. Very good. 5

What are the key specs and build-quality advantages of the Cisco GLC-LH-SMD?

This 1000BASE-LX/LH SFP uses a 1310nm wavelength and supports Digital Optical Monitoring (DOM), so you can monitor transmit and receive optical levels. It is designed for reliable long-term network use and operates in extended temperatures from -5°C to 85°C.

How do I install the GLC-LH-SMD, and do I need any special cable?

Installation is simple: insert the hot-swappable GLC-LH-SMD into an open Gigabit SFP port, connect your dual LC fiber cable, and verify link status. For legacy multimode fiber, use a mode conditioning patch cable to help ensure a stable connection.
