500 m multi-mode SFP module
This Allied Telesis AT-SPSX-90 is a hot-swappable small form-factor pluggable transceiver for Gigabit Ethernet links. It operates at 850 nm wavelength over multi-mode fibre with LC connectors. The module supports distances up to 550 m on 50/125 µm cable or 500 m on 62.5/125 µm cable. It is designed for network equipment that provides an SFP port.
Suits short-haul fibre uplinks.
The module fits builders who need a cost-effective 1000Base-SX link inside a building or campus. It works with any Allied Telesis switch or router that accepts standard SFP transceivers. Buyers who require longer reach beyond 550 m or single-mode fibre compatibility should select a different transceiver type.
850 nm multi-mode reach up to 550 m
The 850 nm wavelength and multi-mode fibre support define the maximum link distance of 550 m on 50/125 µm cable and 500 m on 62.5/125 µm cable. This single optical specification determines whether the module matches the installed fibre plant and required span. Verify your cable type and distance before ordering.

Questions about this item
Which SFP variant should I choose for a 550-metre multi-mode fibre link?
The AT-SPSX-90 is the short-haul 1000Base-SX module rated for 550 m on 50/125 µm fibre and 500 m on 62.5/125 µm fibre at 850 nm.
What does the 550-metre figure mean when the module is installed in a switch?
It is the maximum guaranteed link length over standard multi-mode fibre when the host port operates at 1000Base-SX speeds.
What interface does the module use and what speed does it cap at?
It plugs into any SFP port using an LC duplex connector and runs at a fixed 1000 Mbps Gigabit Ethernet rate.
