AddOn GLC-FE-100BX-U-AO 100BASE-BX SFP TAA | BiDi Fiber Module — GLC-FE-100BX-U-AO

Build compact Fast Ethernet fiber links with a 100BASE-BX SFP transceiver designed for single-strand, bidirectional operation. This AddOn Networks module is compatible with Cisco GLC-FE-100BX-U and supports TAA-compliant procurement requirements, which matters when sourcing for government, education, or regulated enterprise environments. The BiDi design reduces fiber consumption by carrying transmit and receive traffic over a single strand, helping simplify patching and conserve plant capacity in dense closets or remote edge locations. That makes it a strong fit for short Fast Ethernet uplinks, legacy access networks, and installations where you want fiber reach and cleaner cable management without moving to a more complex optics stack. For teams maintaining mixed-generation infrastructure, this module offers a disciplined way to extend or preserve Fast Ethernet connectivity while keeping compatibility and sourcing requirements in view. It is a practical choice when the network needs dependable fiber transport, but the deployment does not justify higher-speed optics or additional cabling overhead. Ideal For Connect remote access devices over single-mode fiber with Fast Ethernet Deploy single-strand uplinks in wiring closets with limited fiber capacity Support regulated procurement workflows that require TAA-compliant hardware Maintain legacy Cisco-compatible Fast Ethernet optics in mixed environments Why This Product 1 Uses one fiber strand instead of duplex cabling 2 Meets TAA compliance requirements for regulated purchasing 3 Supports Fast Ethernet rather than higher-speed optics 4 Fits Cisco GLC-FE-100BX-U-compatible SFP ports
