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

The BlueOptics SFP-BXU34-40KM-DL-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Compact and lightweight with a robust metal housing and a weight of 20 g, the module supports long-distance optical links up to 40 km using an LC simplex connector. The transceiver implements separate transmit and receive wavelengths (1490 nm transmit / 1310 nm receive) and conforms to MSA SFP mechanical and electrical form-factor standards.

Advantages

This BlueOptics SFP transceiver offers compatibility with equipment that supports 1000BASE-BX-U modules while providing a compact metal housing for mechanical durability and thermal stability. The unit supports Digital Diagnostics Monitoring (DDM/DOM) for real-time parameters such as supply voltage, laser bias current, transmit output power, receive input power and temperature when the host device supports DDM. With an MTBF of approximately 1,000,000 hours and quality components selected to MSA standards, the module is intended to deliver stable optical links for extended operational periods.

How to use

Insert the SFP transceiver into a compatible SFP port of a switch, router or media converter while the host device is powered according to the vendor guidelines. Connect an LC simplex single-mode patch cable between this transceiver and the remote BX-U transceiver, ensuring the correct orientation for the separate transmit and receive fibers. Verify link parameters and DDM/DOM values through the host management interface if supported. Follow standard ESD precautions and handle the optical connectors with clean caps to avoid contamination of the optical interface.

Recommendations

For reliable operation, use single-mode fiber and appropriate attenuators or amplifiers if the link budget requires them; ensure the host device supports 1000BASE-BX-U and DDM/DOM if those functions are needed. Clean connectors before mating and store unused transceivers with dust caps to protect the optical interfaces.
