SFP transceiver modul BlueOptics SFP-BXU34-40KM-PS-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-PS-BO is a single‑mode fiber SFP transceiver module designed for point‑to‑point links up to 40 km. Supporting a maximum data rate of 1250 Mbit/s, the module uses an LC simplex connector and a metal silver housing with a compact SFP form factor. It implements 1000BASE‑BX‑U signaling with separate transmit and receive wavelengths for unidirectional transmission on a single fiber and is built to MSA electrical and mechanical standards for broad interoperability.

Advantages

This SFP transceiver provides long‑reach connectivity up to 40 km while maintaining a low power, compact footprint suitable for switches, routers and storage systems. The metal housing offers robust physical protection and heat dissipation, and the module is specified with a high MTBF for reliable, continuous operation in production networks. Digital diagnostics support is available for monitoring key optical and electrical parameters when the host device supports DDM/DOM.

How to use

Insert the SFP module into a compatible SFP slot until it latches. Connect an LC simplex single‑mode patch cord between the module and the remote transceiver, observing correct orientation for the BX transmit and receive fibers. Ensure the host device is configured for 1000BASE‑BX‑U operation and that the remote end uses the complementary BX transceiver (opposite TX/RX wavelengths). If the host supports Digital Diagnostics, enable monitoring to read supply voltage, laser bias current, transmit power, receive power and temperature for link troubleshooting and maintenance.

Recommendations

Use quality single‑mode patch cords and maintain clean LC connectors to ensure optimal optical performance. Verify DDM compatibility with your hardware before relying on diagnostic readings. For best results in mixed‑vendor environments, ensure devices support MSA‑compliant SFP modules and test links after installation to confirm expected throughput and reach.
