Fiber optic transceiver CBO GSLC20-BiDi-B 20 km, BiDi 1310/1550 nm

CBO GSLC20-BiDi-B is a fiber optic transceiver engineered for single-channel bidirectional (BiDi) transmission over single-mode fiber up to 20 km. The module supports two wavelengths (1310 nm and 1550 nm) to enable send and receive on a single fiber, providing media conversion between optical and electrical network interfaces. It is suitable for installations where minimizing fiber count is important, including uplinks, remote device connections and CCTV links that require reliable long-distance optical connectivity.

Advantages

This BlueOptics transceiver reduces fiber infrastructure by using bidirectional transmission on one single-mode fiber, simplifying cable management and lowering deployment cost. The module supports reliable optical performance for links up to 20 km and is compatible with network equipment that accepts standard transceiver form factors and optical interface types. Its use of 1310/1550 nm wavelengths allows interoperability in mixed-wavelength environments and supports long-reach connections without intermediate repeaters.

Suitable for

• Long-distance network uplinks between buildings or sites
• CCTV and video surveillance links requiring single-fiber runs
• Telecom or data links where fiber count must be minimized
• Industrial and ISP access links with single-mode fiber

Key specifications

• Transmission type: single-channel bidirectional (BiDi) over single-mode fiber
• Maximum link distance: up to 20 km
• Operating wavelengths: transmit/receive pair at 1310 nm and 1550 nm
• Optical interface: single-fiber BiDi connector (single-mode)
• Function: media conversion between electrical network ports and optical fiber

How to use

Install the transceiver into a compatible SFP/SFP+ slot or appropriate module cage on the network device following the device manufacturer’s hot-swap guidance. Connect a single-mode fiber cable with the correct BiDi connector to the transceiver, ensuring the correct orientation for transmit and receive wavelengths. Verify link status via the host device LEDs or management interface and test optical power levels and link integrity with suitable optical test equipment. When removing or inserting the module, follow electrostatic discharge precautions and handle fiber connectors by their protective caps to prevent contamination.

Recommendations

Use certified single-mode fiber and clean connectors to maintain optimal optical performance. For distances near the 20 km limit, confirm optical budget and attenuation of the fiber route. When integrating into mixed-vendor networks, check compatibility of wavelength pairing and support for single-fiber BiDi transceivers on both ends of the link.
