Allied Telesis AT-SPFX/15 – 100BASE-FX 15km Single-Mode SFP

Overview

The Allied Telesis AT-SPFX/15 is a 100BASE-FX SFP transceiver that delivers Fast Ethernet over single-mode fibre at distances up to 15 kilometres. It uses an LC connector and operates at a 1310nm wavelength, making it a standard choice for long-reach 100 Mbps fibre links in access and distribution networks. The SFP form factor supports hot-swap operation, allowing the module to be changed in the field without interrupting other system ports. It is well-suited to network edges where 100 Mbps capacity is sufficient and fibre runs exceed the reach of multimode alternatives.

Description

The AT-SPFX/15 addresses the common requirement for 100 Mbps fibre connectivity over distances that multimode fibre cannot support. With a 15km reach over single-mode fibre, it bridges campus buildings, connects remote access layer switches back to a distribution node, or links geographically separated sites where fibre is already in place. The LC duplex connector is the standard interface for modern SFP fibre modules, and the 1310nm wavelength is compatible with common single-mode fibre plant. Operating at 100 Mbps, this transceiver is appropriate for network segments that do not yet require Gigabit capacity, or where legacy 100 Mbps equipment at the far end must be accommodated. The hot-swappable SFP design means failed transceivers can be replaced without taking the host device offline, an important consideration in access networks where a single port may serve many end users. The module is compatible with SFP slots across Allied Telesis switches, media converters, and routers, as well as multi-vendor platforms that conform to the SFP MSA standard.
