## Summary description

CBO GSLC40-BiDi-A-DDM is a fiber optic transceiver designed for single-fiber BiDi links with 1310 nm/1550 nm wavelengths and a reach of up to 40 km. The module supports DDM (Digital Diagnostic Monitoring) for real-time status monitoring. It is intended for long-distance data transmission in access networks, metro links and point-to-point fiber connections, offering reliable optical link performance.

## Long description

CBO GSLC40-BiDi-A-DDM is a fiber optic transceiver designed for single-fiber bidirectional (BiDi) links using 1310 nm and 1550 nm wavelengths with a maximum reach of 40 km. The module integrates Digital Diagnostic Monitoring (DDM) to report real-time operational parameters such as transmit/receive power, temperature and laser bias current. Intended for long-distance data transmission, this transceiver suits access networks, metro links and point-to-point fiber connections that require compact SFP form-factor optics and reliable single-fiber operation.
Advantages
The transceiver supports BiDi operation on a single fiber, reducing fiber count and simplifying installation in fiber-constrained environments. Built-in DDM enables continuous monitoring of optical performance to assist with fault diagnosis and preventive maintenance. Its 40 km reach and compatibility with common SFP slots provide flexible deployment options for service providers and enterprise networks. The device follows standard optical wavelength pairing (1310/1550 nm) for interoperable long-distance links.
Suitable for
Access networks and last-mile fiber connections
Metro ring and inter-office links
Point-to-point links where single-fiber BiDi is required
Network upgrades requiring extended reach up to 40 km
Key specifications
Operating wavelengths: 1310 nm transmit / 1550 nm receive (or vice versa for opposite direction)
Maximum link distance: up to 40 km over single-mode fiber
Form factor: SFP (small form-factor pluggable)
Optical interface: single-fiber BiDi
Monitoring: Digital Diagnostic Monitoring (real-time parameters)
Typical application: single-mode long-distance data transmission
How to use
Install the transceiver into a compatible SFP slot on a switch, router or media converter, ensuring the host device supports BiDi optics. Connect the single fiber between paired BiDi modules, observing correct fiber polarity for the 1310/1550 nm wavelength directions. Verify link establishment and use DDM data provided by the host system to confirm transmit and receive power levels and other diagnostic values. Replace the module with identical wavelength-pair transceivers at the remote end to ensure proper bidirectional communication.
Usage recommendations
Operate the module within the specified fiber type and link length to maintain signal integrity. Use quality single-mode fiber and clean connectors to avoid insertion loss that can affect the 40 km reach. Monitor DDM readings periodically to detect degradation and schedule maintenance if optical power or temperature deviates from expected ranges.
