Maintain reliable short-reach fiber connectivity with the AddOn SFP-GIG-SX-AO. This TAA-compliant 1000BASE-SX SFP transceiver is designed for Alcatel-Lucent compatibility and supports Gigabit Ethernet over multimode fiber through an LC duplex connector. With 850 nm optics and a reach of up to 550 m, it fits the links that keep enterprise access and aggregation layers moving. 1000BASE-SX remains a strong choice for data networking environments where multimode fiber is already in place and predictable performance matters. The module is programmed, uniquely serialized, and tested for data traffic and application compatibility, helping reduce uncertainty during deployment and replacement. For teams managing mixed infrastructure or standardizing on approved sourcing, the TAA-compliant designation adds procurement clarity. This transceiver is built for organizations that want a compatible optics path without sacrificing the discipline of standards-based networking. It is a straightforward fit for switch uplinks, closet interconnects, and other short-reach fiber applications where dependable interoperability is worth paying for.
