Módulo transceptor SFP BlueOptics SFP-BXU34-40KM-IA-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-IA-BO is a single‑mode fiber SFP transceiver module designed for long‑distance optical links with a maximum data rate of 1250 Mbit/s. The module uses an LC simplex connector and supports 1000BASE‑BX‑U operation with separate transmit and receive wavelengths for extended reach up to 40 km. Housed in a metal case and weighing approximately 20 g, the transceiver is intended for integration into switches, routers and other networking equipment that accept MSA‑compliant SFP modules.

Advantages

This SFP transceiver provides reliable single‑fiber bidirectional transmission with a compact SFP form factor and metal housing for mechanical robustness and heat dissipation. With an MTBF of around 1,000,000 hours and support for Digital Diagnostics Monitoring (DDM/DOM) when the host supports it, the module facilitates remote monitoring of optical parameters such as transmit power, receive power and temperature. Compliance with SFP MSA electrical and mechanical standards ensures broad interoperability with compatible networking hardware.

Key specifications

How to use

Install the module into an available SFP port on compatible network equipment, ensuring the host supports 1000BASE‑BX‑U and, if required, DDM/DOM. Connect an LC simplex single‑mode patch cable and verify transmit/receive orientation to match BX‑U single‑fiber operation. After insertion, confirm link status and correct optical power levels via the host device or monitoring tools. Follow the equipment vendor’s guidelines for hot‑plugging and ESD precautions when handling the module.

Recommendations

For optimal performance, use single‑mode fiber with appropriate attenuation budget for 40 km links and high‑quality LC patch cords. Ensure the host device firmware supports third‑party SFP modules and DDM/DOM if remote diagnostics are needed. Avoid excessive bending of fiber and protect transceiver ports from dust by using dust caps when the module is not connected.
