Fiber Optic Transceiver CBO GSLC20-BiDi-A 20 km, 1310 nm/1550 nm

CBO GSLC20-BiDi-A is a compact fiber optic BiDi transceiver module designed for single-fiber point-to-point links with a maximum reach of 20 km. The module supports bidirectional transmission on a single core by using two wavelengths: 1310 nm and 1550 nm. It is supplied in an SFP-style form factor to fit compatible network equipment and delivers optical connectivity suitable for telecom and enterprise links that require long-distance single-fiber connections.

Advantages

The BiDi design reduces fiber cabling by enabling transmit and receive channels over a single fiber, simplifying installation and lowering cabling costs. Its SFP-compatible form factor allows hot-swappable deployment in a wide range of switches, routers and media converters. Operating wavelengths of 1310 nm and 1550 nm provide reliable optical transmission over distances up to 20 km, while the module’s compact size and standardized interface ensure compatibility with common network platforms.

Suitable for

• Point-to-point fiber links where only a single fiber is available
• Last-mile connections between buildings or sites up to 20 km apart
• Integration into switches, routers or media converters with SFP ports
• Telecom and enterprise backbone or distribution links requiring optical reach

Key specifications

• Optical mode: Single-mode fiber (SMF)
• Wavelengths: 1310 nm and 1550 nm (bi-directional operation)
• Maximum reach: 20 km
• Form factor: SFP-style transceiver
• Connector type: LC duplex (single-fiber BiDi uses LC connector)
• Transmission type: Point-to-point bidirectional optical link
• Typical applications: Telecom and enterprise optical links

How to use

Insert the SFP-style transceiver into a compatible SFP port on your switch, router or media converter while the device is powered on or off based on the host device instructions. Connect the single-mode fiber with an LC connector to the module, ensuring correct orientation for the BiDi wavelengths (transmit/receive alignment). Configure the host network interface for the appropriate port settings and verify link status through the device management interface. Monitor optical link parameters and perform standard network testing to confirm data transmission over the intended 20 km span.

Recommendations

Use factory-tested single-mode fiber and quality LC connectors to maintain optimal link performance. Observe ESD precautions when handling the transceiver and avoid bending the fiber beyond recommended radii. Verify compatibility of the SFP module with the host device and consult the equipment vendor’s documentation for any platform-specific settings or supported transceiver lists.
