SFP-transceivermodule BlueOptics SFP-BXU35-40KM-NA-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-NA-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. Housed in metal and weighing approximately 20 g, this compact SFP module provides a duplex-capable link using an LC simplex connector and supports long-reach transmission up to 40 km with separate transmit and receive wavelengths (TX 1550 nm / RX 1310 nm). The module follows MSA SFP form-factor standards and includes Digital Diagnostic Monitoring (DDM/DOM) support when the host hardware provides the required interface.

Advantages

The transceiver offers stable single-mode optical transmission for Ethernet and related protocols at up to 1.25 Gbit/s over distances to 40 km, with an MTBF rating of 1,000,000 hours indicating long operational life. Its metal housing and standardized SFP interface ensure mechanical robustness and wide interoperability with equipment that accepts MSA-compliant SFP modules. Integrated DDM/DOM support enables real-time monitoring of parameters such as optical output power and temperature when used with compatible systems.

How to use

Install the BlueOptics SFP-BXU35-40KM-NA-BO into an empty SFP port on a compliant switch, router or storage device while the host system is powered off or following the vendor’s hot-plug instructions. Connect a single-mode LC patch cable to the LC simplex connector and route the fiber to the remote transceiver; ensure TX of one end is connected to RX of the other end. Configure the host port for 1000BASE-BX-U operation as required by the hardware vendor and verify link status. If available, enable DDM/DOM in the management interface to monitor optical parameters remotely.

Recommendations

Use single-mode fiber rated for long-reach links and LC simplex connectors to achieve the specified 40 km range. Verify compatibility with the specific hardware platform and firmware version, and test a sample module in your environment before large deployments. Maintain proper fiber handling and cleanliness for optimal optical performance.
