Cisco GLC-BX-D SFP Module : BiDi Single-Fiber , 10km Reach , DDM Support Cisco Module
 

The Cisco GLC-BX-D is a high-performance SFP (Small Form-Factor Pluggable) transceiver designed for single-fiber bidirectional (BiDi) communication, optimizing fiber infrastructure while reducing costs. Compatible with Cisco switches and routers, this module is ideal for enterprise networks, data centers, and service providers requiring reliable 1.25Gbps connectivity over 10km.

Key Features & Benefits

1. BiDi Single-Fiber Technology

   • Uses WDM (Wavelength Division Multiplexing) to transmit and receive signals over a single strand of single-mode fiber (SMF).

   • Tx: 1310nm / Rx: 1490nm wavelengths (paired with GLC-BX-U for reverse direction).

   • Saves 50% fiber costs compared to dual-fiber solutions.

2. 10km Long-Distance Reach

   • Supports up to 10 kilometers on single-mode fiber, ideal for metro access, campus networks, and FTTH.

3. Digital Diagnostics Monitoring (DDM)

   • Real-time monitoring of temperature, optical power, voltage, and bias current for proactive maintenance.

4. Low Power & High Compatibility

   • Low power consumption (<1W) and hot-swappable for easy deployment.

   • Certified for Cisco Catalyst, Nexus, and MDS series switches (verify compatibility).
