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

The BlueOptics SFP-BXU34-40KM-PA-BO is a single‑mode fiber SFP transceiver module designed for 1000BASE‑BX‑U applications with a maximum data transfer rate of 1250 Mbit/s. The module features a metal housing in silver colour, LC simplex optical interface, and a compact form factor suitable for SFP slots. It supports single‑fiber bidirectional transmission with separate transmit and receive wavelengths and includes Digital Diagnostics Monitoring (DDM) for real‑time link parameters.

Advantages

This SFP module provides a standard MSA‑compliant SFP interface for broad interoperability with networking hardware that supports 1000BASE‑BX‑U optics. The metal housing delivers mechanical robustness and thermal stability while the module’s rated MTBF of 1,000,000 hours indicates long service life and low maintenance requirements. Digital Diagnostics Monitoring enables remote monitoring of supply voltage, laser bias current, transmit power, receive power and temperature to simplify troubleshooting and link maintenance.

How to use

Insert the BlueOptics SFP module into a compatible SFP slot on your switch, router or other network device while the device is powered according to the vendor’s instructions. Connect an appropriate single‑mode LC simplex fiber patchcord between the module and the remote transceiver, ensuring correct orientation for the transmit and receive fibers. Verify the link status via device LEDs or management interface and, if supported, monitor real‑time diagnostics through the host equipment to confirm nominal supply voltage, optical power levels and temperature.

Recommendations

Ensure the host device supports 1000BASE‑BX‑U and DDM if you plan to use the monitoring functions. Use quality single‑mode fiber and LC simplex patchcords, follow proper fiber handling procedures to avoid contamination, and perform optical power checks during installation to validate link performance up to 40 km.
