Cisco GLC-BX-D 1000BASE-BX10-D BiDi SFP Transceiver

The Cisco GLC-BX-D is factory-original single-fiber bidirectional(BiDi) Gigabit SFP transceiver, downstream model of BX10 series. It realizes bidirectional transmit/receive signal over one single-core single-mode fiber, needs to pair with matching GLC-BX-U for end-to-end link, max reach up to 10km, integrated DOM digital optical monitoring function.

✅ Single Fiber Bidirectional Design Saves half fiber resource, uses one single fiber to finish send & receive data, greatly reduces cabling cost for FTTH, building interconnection. ✅ Pair Required Working GLC-BX-D (D 端：发 1550 收 1310) + GLC-BX-U (U 端：发 1310 收 1550) must be used as a pair at two ends of fiber link. ✅ DOM Real-time Monitoring Monitor Tx/Rx optical power, module temperature, supply voltage via Cisco IOS for daily maintenance & fault diagnosis. ✅ Hot Plug SFP Standard Hot-swappable without powering off switch/route equipment, convenient onsite replacement. ✅ Full Cisco IOS Compatible Plug&play on Catalyst 2960/3560/3750 & ISR router series, no extra configuration needed.
