Deliver 1 GbE connectivity across extended optical spans with the AXIOM 1000BASE-BX80-U SFP for Alcatel. This bidirectional transceiver is built for single-fiber operation, helping network teams conserve fiber strands and simplify long-run deployments without changing the Ethernet speed profile. The BX80-U designation points to an 80 km reach class, which places this module in a different tier from standard short-reach optics. It is suited to long campus backbones, remote building interconnects, and other transport paths where distance pushes beyond conventional access optics. The LC connector keeps the physical interface familiar, while the SFP form factor supports straightforward integration into compatible Alcatel platforms. For infrastructure teams, the value is in precision. You get the reach class needed for demanding optical paths without paying for excess bandwidth or oversized hardware. That makes this module a practical choice when the network design calls for long-distance 1 GbE transport, careful fiber planning, and compatibility with existing Alcatel-based environments.
