Build short-reach fiber links with a transceiver designed for straightforward integration and dependable day-to-day operation. This AddOn 1000BASE-SX SFP supports Gigabit Ethernet over multi-mode fiber and uses an LC connector, making it a strong match for access switches, aggregation layers, and intra-building runs where simplicity and compatibility are priorities. The module is compatible with Allied Telesis AT-SPSX environments and is TAA compliant, which helps procurement teams meet sourcing requirements without moving to a more expensive platform refresh. For organizations standardizing on multi-mode fiber, SX optics remain a sensible choice for predictable short-distance performance and easy deployment. Hot-swappable design supports maintenance windows that need to stay short. That matters when ports are already in service and downtime is measured in minutes, not hours. Instead of overbuying long-reach optics for a short link, this module keeps the design aligned to the actual distance and the actual application. For enterprise networks, branch aggregation, and controlled facility environments, the value is in precision: the right reach, the right connector, and the right compatibility profile for the switch already in place.
