Axiom GLC-BX80-U-I-AX 1000BASE-BX80-U SFP for Cisco | SFP Modules — GLC-BX80-U-I-AX

Keep remote sites, campus buildings, and aggregation points connected with a transceiver designed for long-reach Gigabit transport. The Axiom 1000BASE-BX80-U SFP for Cisco supports 1000BASE-BX80-U links over single-mode fiber, giving network teams a practical option for extending Ethernet beyond the limits of standard SX and LX optics. This module is built for environments where distance matters and link stability cannot be left to chance. Its bidirectional design reduces fiber strand requirements while preserving the throughput expected from 1 GbE infrastructure. That makes it a strong fit for access-layer uplinks, carrier handoffs, and inter-building connections where every port and every strand has value. For teams standardizing on Cisco-compatible optics, this Axiom module offers a straightforward path to long-reach deployment without changing the network design. It is suited to infrastructure that needs dependable transport, predictable interoperability, and a clean fit into existing SFP-based hardware. When the cost of a missed link is higher than the cost of the optic, this is the class of component that earns its place. Ideal For Inter-building uplinks between campus network closets Long-distance access-layer connections in metro edge networks Point-to-point fiber links where strand count is limited Aggregation uplinks for remote cabinets and distributed sites Why This Product 1 Longer reach than standard SX and LX SFP optics 2 Bidirectional design reduces fiber strand requirements 3 Cisco-compatible fit for existing SFP infrastructure 4 Built for single-mode long-haul access links
