AddOn GLC-SX-MM-AO SFP Transceiver

The AddOn GLC-SX-MM-AO is a Cisco-compatible SFP transceiver built for 1-Gigabit Ethernet links over multi-mode fibre. It suits network engineers who need a drop-in replacement for the Cisco GLC-SX-MM part number in enterprise switches or routers.

Build Quality and Daily Use

The module uses the industry-standard SFP form factor with an LC duplex connector for multi-mode fibre patch cables. Because it is factory-loaded with Cisco-specific configuration data, it initialises identically to the OEM transceiver and can be mixed with other vendor modules without extra configuration steps.

Deciding Specification

The transceiver operates at an 850 nm wavelength and reaches 550 metres on multi-mode fibre at 1000 Mbps. Buyers who need longer reach or single-mode fibre support should select a different module.

Questions about this item

What distance does the 1000 Base-SX interface support over multi-mode fiber at 850 nm?

The transceiver reaches 550 m over multi-mode fiber at 850 nm wavelength.

What connector and form factor are required to install this module?

It uses an LC duplex connector and the standard SFP form factor.

How is the transceiver installed and what common step is missed?

Insert the SFP module into the switch port until it clicks, then attach the LC fiber cables; the step often missed is removing the dust caps from both the module and the cables before connecting.
