This high-performance 1000BASE-BX10-U BiDi SFP transceiver is engineered for cost-effective single-mode fiber deployments, delivering reliable connectivity up to 20 kilometers over a single fiber strand. Using advanced WDM (Wavelength Division Multiplexing) technology, it transmits at 1310nm and receives at 1490nm, enabling bidirectional communication that reduces fiber infrastructure costs by 50%.

The module features full DOM (Digital Optical Monitoring) support per SFF-8472 standards, enabling real-time monitoring of critical parameters, including optical power, temperature, and voltage, through most network management systems. This allows for proactive diagnostics and simplified troubleshooting.

Fully compatible with Cisco switches and MSA (uncoded) standards, this transceiver serves as a direct replacement for Cisco's GLC-BX-U module, offering exceptional value without compromising performance or reliability.

Important Note: BiDi transceivers must be deployed in pairs - this GLC-BX-U (upstream) module pairs with a GLC-BX-D (downstream) module which uses opposite wavelengths (TX1490/RX1310). The two modules work together to create a complete bidirectional link over a single fiber.
