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

The BlueOptics SFP-BXU35-40KM-AL-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑BX‑U links with a maximum data transfer rate of 1250 Mbit/s. The module comes in a metal housing, has a silver colour and a compact form factor with a weight of 20 g. It supports long‑distance optical transmission up to 40 kilometres using LC simplex connectors and implements proven SFP MSA electrical and mechanical compatibility for plug‑and‑play use in supporting network equipment.

Advantages

This SFP transceiver provides bidirectional single‑fibre transmission with separate transmit and receive wavelengths (typically 1550 nm transmitter / 1310 nm receiver) for 1000BASE‑BX‑U applications, enabling long reach over single‑mode fiber. The metal housing ensures mechanical robustness and thermal stability, while an MTBF rating of 1,000,000 hours indicates long operational lifetime and reduced maintenance. The module supports Digital Diagnostics Monitoring (DDM/DOM) where supported by the host device, allowing remote readout of key optical and electrical parameters.

How to use

Install the SFP transceiver into a compatible SFP slot on your switch, router or storage device ensuring the host supports 1000BASE‑BX‑U modules. Connect the LC simplex fiber patch cable to the module and verify the correct fibre orientation for the bidirectional link (one fiber used for both transmit and receive with opposite wavelengths). Configure the host interface according to network requirements (speed, duplex, and any link‑specific settings) and check DDM/DOM readings through the host management interface if monitoring is required.

Recommendations

Ensure the host device firmware and driver environment supports third‑party SFP modules and DDM/DOM if you need real‑time diagnostics. Use single‑mode LC simplex fiber of appropriate quality, keep connectors clean, and follow ESD precautions during installation to maintain link reliability and achieve the specified 40 km reach.
