Cisco-compatible 1 Gbps SFP transceiver

This AddOn GLC-LH-SMD-AO is a hot-swappable SFP module built for 1000Base-LX links over single-mode fibre. It targets network engineers and integrators who need a drop-in replacement for Cisco GLC-LH-SMD optics in switches, routers or media converters running at 1 Gbps.

Upgrades legacy copper or short-reach optics

The module replaces fixed copper ports or multi-mode SFPs when the link must span up to 10 km at 1310 nm. The jump is worth it when existing cabling is single-mode and the budget calls for a TAA-compliant, MSA-standard part that initialises identically to the OEM unit.

Hot-swap install into any SFP cage

Insert the transceiver into a powered Gigabit Ethernet SFP slot; the LC connectors key automatically and the DOM interface reports link health. The usual pitfall is mating angle-polished connectors to flat-polished patch cords, which raises return loss and drops the link.

Questions about this item

What type of fiber connector does the GLC-LH-SMD-AO transceiver use?

The module uses a duplex LC connector for single-mode fiber patch cables.

How is the SFP module installed and what step is often missed?

Insert the transceiver into a compatible Gigabit SFP port until it clicks; the latch must be fully engaged or the link will not come up.

What ongoing maintenance does the 1310nm single-mode transceiver require?

Inspect and clean the LC ferrule end-faces before each connection; replace the module if optical power degrades below the 10km link budget.
