Fiber optic transceiver module BlueOptics GLC-2BX-U-40KM-BO 1250 Mbit/s cSFP

The BlueOptics GLC-2BX-U-40KM-BO fiber optic transceiver module provides single-channel bidirectional data transmission with a cSFP interface and a maximum data rate of 1250 Mbit/s. Designed for network equipment that requires compact, lightweight optical modules, this transceiver supports point-to-point links up to 40 km. The module's silver housing and 20 g weight make it straightforward to install in compatible cSFP slots while maintaining standard form-factor compatibility.

Advantages

The transceiver offers a predictable optical solution for long-distance connectivity up to 40 km without additional converters. Its compact cSFP form factor allows easy integration into switches, routers or media converters that accept cSFP modules. With a specified maximum data transfer rate of 1250 Mbit/s, the unit supports common serial and low-speed gigabit links where a single-channel fiber connection is required.

How to use

Insert the BlueOptics cSFP transceiver into a compatible cSFP slot on the network device until it seats firmly. Connect single-mode fiber patch cords according to the module's TX/RX orientation and verify that connectors are clean before mating. After installation, enable or configure the corresponding port in the device management interface and check link status LEDs or system logs to confirm stable operation at up to 1250 Mbit/s. Follow standard handling procedures for optical modules to avoid electrostatic discharge or connector contamination.

Recommendations

Use single-mode fiber rated for the intended distance and keep connectors clean using appropriate cleaning tools. Verify compatibility with your host device's cSFP specifications and firmware; perform link tests after installation to confirm signal integrity over the required 40 km span.
