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

The BlueOptics SFP-BXU34-40KM-VA-BO is a single-mode fiber SFP transceiver module designed for long-distance optical links. Supporting a maximum data rate of 1250 Mbit/s (1000BASE-BX-U) and an LC simplex connector, this compact module in a metal housing provides robust physical protection and an MTBF of 1,000,000 hours. It supports single-fiber bidirectional transmission with separate transmit and receive wavelengths and is suitable for integration into equipment that follows the SFP MSA standard.

Advantages

This BlueOptics SFP transceiver offers compatibility with MSA-compliant SFP ports and supports established high-speed protocols up to 1.25 Gbit/s over distances up to 40 km on single-mode fiber. The metal housing increases mechanical durability while the low weight (0.02 kg) simplifies handling and installation. Digital diagnostics (DDM/DOM) support enables remote monitoring of supply voltage, laser bias current, optical transmit/receive power and temperature where host hardware provides that functionality.

Key specifications

How to use

Install the module into a compatible SFP slot while the host device is powered on or according to the host vendor's hot-plug procedures. Use an LC simplex single-mode patch cord and, for bidirectional links, connect to a matching BX-U transceiver on the remote end with the complementary wavelength orientation. Verify link parameters and, if available, enable and read DDM/DOM information from the host management interface to monitor optical power, temperature and supply metrics. Follow the network equipment vendor instructions for interface configuration (speed, duplex and protocol settings) as required.

Recommendations

Ensure the host hardware officially supports MSA-compliant third-party SFP modules and that DDM/DOM is supported if remote diagnostics are required. Use appropriate single-mode fiber and LC connectors, maintain clean connector end-faces, and follow ESD precautions during handling. For optimal performance over the full 40 km range, use certified single-mode patch cords and verify link loss budgets before deployment.
