Cisco GLC-BX80-D-I-RF 1000BASE-BX80 SFP 1570 nm | Enterprise Fiber — GLC-BX80-D-I-RF

Keep critical Gigabit links up across long distances with the Cisco GLC-BX80-D-I-RF. This remanufactured 1000BASE-BX80 SFP is designed for single-mode fiber deployments that need extended reach up to 80 km, making it a strong fit for campus backbones, remote buildings, and metro interconnects. Operating at 1 Gbps with a 1570 nm wavelength, this transceiver supports bidirectional fiber architectures that reduce strand count while preserving the reach required for distributed infrastructure. The SFP form factor makes it easy to deploy in compatible Cisco platforms where space, power, and optics consistency matter. For teams balancing performance and procurement discipline, remanufactured optics can deliver the right economics without changing the network design. This module is suited to environments that already standardize on Cisco hardware and need a long-reach Gigabit optic that fits established operational patterns. Choose this model when the link budget is tight, the distance is real, and the cost of downtime is higher than the cost of the optic. Ideal For Connect campus buildings over long single-mode fiber runs Link remote network rooms to a central core over metro distances Support inter-building backbone connections in enterprise environments Replace failed long-reach Gigabit optics in Cisco-based infrastructure Why This Product 1 Longer reach than standard Gigabit SFP optics 2 Lower fiber strand count than duplex alternatives 3 Remanufactured pricing versus new Cisco optics 4 Built for Cisco-compatible enterprise deployments
