Fiber optic transceiver CBO GSLC80-DDM — single-channel 1550 nm, up to 80 km, DDM

CBO GSLC80-DDM is a single-channel fiber optic transceiver that transmits at 1550 nm and is engineered for long-distance optical links up to 80 km. The module provides a single-wavelength connection suitable for CWDM and long‑haul applications, and includes Digital Diagnostic Monitoring (DDM) to report real-time optical parameters such as transmit and receive power, temperature, and laser bias. Designed for compatibility with standard SFP form factors, this transceiver is intended for use in telecom, data center uplinks, and enterprise network segments that require stable long-reach connectivity and live diagnostics.

Advantages

The transceiver supports single-channel 1550 nm operation for minimal wavelength interference and optimized long-distance performance. Integrated DDM enables remote monitoring of key optical metrics to aid in troubleshooting and preventive maintenance. The module’s design focuses on reliable long-reach transmission up to 80 km over single-mode fiber, delivering consistent signal quality for point-to-point links. Physical compatibility with common SFP ports ensures straightforward installation and replacement in network equipment.

Suitable for

• Long-distance point-to-point fiber links up to 80 km
• CWDM and long‑haul single-wavelength deployments
• Telecom and service provider backbone connections
• Enterprise campus or data center uplinks requiring diagnostics

Key specifications

How to use

Install the transceiver into a compatible SFP slot on the network device with the device powered according to the equipment manufacturer’s guidelines. Connect single‑mode fiber using appropriate connectors and ensure correct transmit/receive orientation. Verify link status via the network device interface and use the DDM functions to read optical power levels, temperature, and other diagnostics for link validation. Follow standard electrostatic discharge (ESD) precautions and keep protective caps on fiber connectors when not in use.

Usage recommendations

For stable long-reach performance, use certified single-mode fiber and ensure connectors and splices meet loss budgets for 80 km links. Monitor DDM parameters periodically to detect gradual signal degradation and plan maintenance; if optical power margins approach threshold levels, inspect connectors and fiber continuity before replacing hardware.
