SFP transceiver module BlueOptics SFP-BXU34-40KM-MT-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-MT-BO is an SFP fiber-optic transceiver module designed for single-mode links with up to 1250 Mbit/s data rate and a reach of up to 40 km. The module uses an LC simplex connector and follows MSA SFP mechanical and electrical standards, providing interoperability with hardware that supports 1000BASE-BX-U optics. Encased in a metal housing and weighing 20 g, it offers a compact, industry-standard form factor with an MTBF rating of approximately 1,000,000 hours for long-term operation.

Advantages

The module supports 1000BASE-BX-U operation with separate transmit and receive wavelengths optimized for single-mode fiber, enabling simultaneous send/receive over a single strand. Compliance with SFP MSA ensures wide compatibility across routers, switches and other network devices that accept SFP modules. A metal enclosure provides mechanical protection and thermal stability while the built-in digital diagnostics (DDM/DOM) capability enables remote monitoring of parameters such as supply voltage, laser bias current, optical output and receive power, and temperature where supported by the host device.

Key specifications

How to use

Install the SFP transceiver into an available SFP port on a switch, router or other network device that supports 1000BASE-BX-U optics. Connect an LC simplex single-mode patch cord, observing correct orientation for the transmit and receive ends. Verify link status on the host device and, if available, enable or read DDM/DOM parameters for real-time diagnostics. Ensure the host platform supports the required wavelengths and optical protocol prior to deployment.

Recommendations

Use certified single-mode LC simplex patch cords and follow the host vendor’s compatibility list when deploying the module. Keep connectors clean and observe standard fiber handling procedures to maintain signal quality. If DDM is required, confirm host support and verify diagnostics during commissioning and periodic maintenance.
