SFP transceiver BlueOptics MGBIC-BX40-U-EN-BO 1250 Mbit/s

The BlueOptics MGBIC-BX40-U-EN-BO SFP transceiver is a compact fiber optic module designed for 1250 Mbit/s data links. It uses an SFP interface in a silver housing and implements 1000BASE-BX-U optical signalling with LC simplex connection. The module transmits at 1310 nm and receives at 1550 nm, enabling bidirectional transmission over a single fiber and reducing cabling complexity. Built to MSA form-factor standards and compliant with CE, RoHS and FCC, this transceiver targets reliable point-to-point fiber connections in switches, routers and other network appliances.

Advantages

The transceiver offers a high mean time between failures (MTBF) of around 3,000,000 hours for extended service life and reduced maintenance. Compatibility with MSA-compliant LC simplex ports ensures broad hardware support, while support for Digital Diagnostics Monitoring (DDM/DOM) provides real-time telemetry such as supply voltage, laser current, optical power and temperature for easier monitoring and troubleshooting. The compact SFP form factor simplifies installation and upgrade paths in existing network racks.

Suitable for

• Point-to-point fiber links between switches and routers
• Data center uplinks and server connectivity
• WAN connections over single-fiber infrastructure
• Replacement or expansion of existing SFP ports in network equipment

How to use

Insert the BlueOptics SFP transceiver into a compatible SFP slot on your switch, router or other network device until it clicks into place. Connect an LC simplex fiber patch cable between the transceiver and the remote transceiver, ensuring correct orientation for transmit and receive fibers as required by 1000BASE-BX-U (single-fiber bidirectional). Verify that the host device recognizes the module and, if needed, enable or verify DDM/DOM telemetry in the management interface to monitor operating parameters. Follow equipment vendor instructions for safe insertion and removal to avoid damaging the fiber connector or module.

Usage recommendations

Use high-quality single-fiber LC simplex patch cables and maintain proper fiber cleanliness to ensure optimal signal quality. Confirm that the host hardware supports 1000BASE-BX-U and DDM/DOM if remote diagnostics are required. For long-term reliability, avoid sharp bends and excessive tensile stress on fiber cabling and operate the module within the manufacturer’s recommended temperature range.
