Axiom GLC-2BX-D-AX 1000BASE-BX SFP 10 km | Cisco, BiDi, LC — GLC-2BX-D-AX

Keep critical Ethernet links running across longer single-mode runs without adding extra fiber pairs. The Axiom GLC-2BX-D-AX 1000BASE-BX SFP uses bidirectional optics to transmit at 1,490 nm and receive at 1,310 nm, delivering 1 Gbps connectivity over distances up to 10 km. This compact transceiver is designed for Cisco-compatible deployments where port density, fiber conservation, and predictable link performance matter. By carrying traffic in both directions over a single strand of SMF, it helps reduce cabling complexity while preserving the reach needed for campus backbones, building-to-building links, and remote access aggregation. For teams standardizing on proven optics rather than overspending on unnecessary features, this module offers a practical fit for production networks that need dependable Gigabit transport. It is a straightforward choice for replacing aging transceivers, expanding switch uplinks, or adding long-reach connectivity in environments where every fiber strand counts. Ideal For Campus backbone uplinks between distribution switches Building-to-building fiber runs across a corporate site Long-reach access aggregation in enterprise networks Replacement optics for Cisco switch ports Why This Product 1 BiDi optics reduce fiber strand requirements versus standard duplex SFPs 2 10 km reach suits campus and building interconnects 3 Cisco compatibility supports straightforward replacement planning 4 Compact SFP design fits high-density switch ports
