Cisco GLC-BX-U 1000BASE-BX SFP Transceiver
Brand: Cisco (or Compatible Manufacturer) · SKU: GLC-BX-U · MPN: GLC-BX-U · Category: Networking
The GLC-BX-U is a 1G SFP (Small Form-Factor Pluggable) transceiver designed for bidirectional single-mode fiber (SMF) transmission, compatible with Cisco devices. It utilizes BiDi technology, requiring only a single strand of fiber. It transmits at 1310nm (Tx) and receives at 1490nm (Rx) wavelengths, supporting data rates up to 1.25 Gbps (typically 1000BASE Ethernet/Gigabit Ethernet or 1G Fiber Channel) over distances up to 10 km or 20 km depending on the source/compatible unit specifications. It features an LC connector and supports Digital Optical Monitoring (DOM/DDM). It is suitable for applications in Enterprise LAN Networks, Data Center LAN Networks, and ISP communication links. Compatible versions are generally CE/RoHS certified and comply with SFP MSA standards (SFF-8477).
