SFP transceiver module BlueOptics SFP-BXU35-40KM-RW-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-RW-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data transfer rate of 1250 Mbit/s. The module uses an LC simplex connector and supports long-distance links up to 40 km using a 1310 nm receiver and a 1550 nm transmitter. Constructed with a metal housing and weighing 20 g, it provides a compact, MSA-compliant form factor suitable for use in switches, routers, storage systems and other networking equipment that accept standard SFP modules.

Advantages

The transceiver supports Duplex operation on a single fiber pair using separate transmit and receive wavelengths and is compatible with MSA SFP interfaces, enabling interoperability across a broad range of hardware. Built with tested components and DDM/DOM support, it offers real-time monitoring of supply voltage, laser bias current, optical output/input power and temperature where the host supports these features. The metal housing provides mechanical robustness while the listed MTBF of 1,000,000 hours indicates design for long operational lifetime.

How to use

Install the BlueOptics SFP-BXU35-40KM-RW-BO by inserting the module into a compatible SFP port until it latches. Connect an appropriate single-mode LC patch cable or patch panel to the LC simplex connector, ensuring transmit and receive ends are correctly oriented for the BX-U single-fiber topology. Verify link status on the host device and, if available, use the host management interface to read DDM/DOM parameters for diagnostics. Follow your hardware vendor’s guidance for hot-plugging and firmware compatibility to ensure reliable operation.

Recommendations

Use quality single-mode fiber and approved LC simplex patch cords to achieve the specified 40 km reach. Confirm that the host device supports 1000BASE-BX-U and DDM/DOM if you require digital monitoring. Avoid excessive bending of fiber and protect connectors from contamination to maintain signal integrity.
