Allied Telesis 1000Base-SX Expansion Module, 1-Port

Extend critical network paths with the Allied Telesis 1000Base-SX Expansion Module. Built for the AT-8324SX Fast Ethernet Switch, this single-port module adds 1000Base-SX connectivity over multi-mode optical fiber, giving infrastructure teams a practical way to expand backbone capacity without replacing the core switch. Use it to connect remote sites, add high-speed servers, or build a Fast Ethernet or Gigabit Ethernet backbone where short-to-medium fiber runs are required. The 0.55 km maximum distance supports structured campus and building deployments where copper is no longer enough and predictable fiber performance matters. This module is a focused expansion choice for environments that need dependable optical connectivity and straightforward integration. The lifetime warranty adds long-term value for teams standardizing on Allied Telesis hardware and planning around stable network growth rather than short-term patchwork upgrades.
