## Summary description

CBO GSLC40-BiDi-B-DDM is a fiber optic transceiver designed for single-fiber BiDi links with a 1310 nm wavelength and a reach of up to 40 km. It supports Digital Diagnostic Monitoring (DDM) for real-time optical parameter reporting. Intended for telecom and data network use, it enables long-distance single-fiber connections and simplifies monitoring and maintenance.

## Long description

The Optical Transceiver CBO GSLC40-BiDi-B-DDM is a single-fiber bidirectional (BiDi) SFP module operating at 1310 nm and designed for point-to-point fiber links up to 40 km. It integrates Digital Diagnostic Monitoring (DDM) to report real-time optical parameters such as transmit/receive power and temperature, allowing easier diagnostics and maintenance in telecom and data network environments. The module supports standard SFP form factor connectivity and is intended for use in equipment that accepts SFP BiDi transceivers.
Advantages
This transceiver reduces fiber infrastructure requirements by enabling single-fiber BiDi operation, cutting cable and deployment complexity in long-distance links. The 1310 nm wavelength and 40 km reach make it suitable for metro and access networks where extended range and reliable performance are needed. Integrated DDM provides continuous monitoring of optical status for proactive fault detection and network management without additional hardware.
Suitable for
Point-to-point single-fiber links in metro and access networks
Telecom aggregation and carrier ethernet connections
Data center uplinks where single-fiber routing is required
Network segments that require remote optical monitoring
Key specifications
Wavelength: 1310 nm
Transmission distance: up to 40 km over single-mode fiber
Interface: SFP form factor for hot-pluggable installation
Bidirectional operation: single-fiber BiDi (separate Tx/Rx wavelengths on same fiber)
Digital Diagnostic Monitoring (DDM): real-time monitoring of optical parameters
Compatibility: designed for standard SFP ports supporting BiDi transceivers
How to use
Install the transceiver into a compatible SFP slot on network equipment following the device manufacturer’s hot-plug guidelines. Connect a single-mode fiber with the correct BiDi passive splitter or proper fiber connector configuration to carry both transmit and receive signals on one fiber. Configure network equipment interfaces as required; many systems will auto-negotiate link parameters, while others may require manual interface setup. Use management tools or the DDM readout to verify optical power levels and temperature after installation.
Usage recommendations
For reliable operation, use single-mode fiber rated for the intended distance and ensure connectors are clean and properly seated. Verify that the transceiver’s Tx/Rx orientation matches the remote module to establish the BiDi link. Monitor DDM values periodically to detect signal degradation early and plan maintenance if optical power or temperature readings fall outside expected ranges.
