Cisco 1000BASE-BX SFP Transceiver (Multiple Variants Exist)
Brand: Cisco (and compatible manufacturers) · SKU: GLC-BX · MPN: GLC-BX (Series) · Category: Networking
The GLC-BX is a generic reference for a Cisco 1000BASE-BX SFP transceiver module, which is designed for bidirectional single-mode fiber (SMF) transmission using Wavelength Division Multiplexing (WDM) over a single fiber strand. Specific part numbers like GLC-BX-U (Upstream) and GLC-BX-D (Downstream) exist, supporting different wavelength pairs and often specifying a maximum distance of 10km or more (e.g., 40km, 80km). These modules are hot-pluggable, support Gigabit Ethernet (1.25 Gbps line rate), and typically include Digital Optical Monitoring (DOM) functions for real-time parameter tracking (optical power, temperature, voltage, etc.). They use an LC simplex connector. The upstream (U) variant often transmits at 1490nm and receives at 1310nm, while the downstream (D) variant does the reverse.
