Product Identity

The AddOn GLC-LH-SM-AO is a 1000Base-LX SFP transceiver built for Gigabit Ethernet links over single-mode fiber. It targets network engineers who need a Cisco-compatible module for campus or metro connections.

Thermals Noise Power

The module follows the SFP multi-source agreement, so it draws standard power and runs within normal switch thermal limits without extra cooling. Operation is silent because the unit has no moving parts.

Deciding Specification

The 10 km reach at 1310 nm wavelength on LC single-mode fiber determines whether this transceiver fits the link budget. Buyers who need longer distance or multi-mode support must choose a different module.

Questions about this item

How do I install this SFP transceiver into a Gigabit Ethernet slot and which step is often missed?

Insert the module until it clicks into the SFP cage, then lock the LC single-mode fiber cables; the step often missed is fully seating the latch before cabling.

What maintenance or replacement will this non-DOM transceiver need over time?

No firmware updates are required; plan to replace the unit if link errors appear or after a hardware refresh cycle.

What limit appears first during sustained 1000 Base traffic over 10 km single-mode fiber?

The optical link budget at 1310 nm sets the practical ceiling; signal attenuation beyond 10 km will degrade the connection first.
