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

The BlueOptics SFP-BXU34-40KM-SS-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑BX‑U links with a maximum data rate of 1250 Mbit/s. The module uses an LC simplex connector and a metal housing, weighs approximately 20 g, and is built to meet MSA mechanical and electrical standards. It supports long‑reach transmission up to 40 km over single‑mode fiber and includes Digital Diagnostics Monitoring (DDM/DOM) functionality when supported by the host hardware.

Advantages

The module offers a compact SFP form factor with an industry‑standard LC simplex optical interface, allowing interoperability with networking equipment that supports 1000BASE‑BX‑U SFP transceivers. Its metal housing provides mechanical robustness and thermal stability. Built to MSA compliance and tested for compatibility, the transceiver delivers stable optical performance for Ethernet and related high‑speed applications while providing DDM for remote monitoring of signal and module parameters.

Key specifications

How to use

Install the SFP transceiver into a compatible SFP port on switches, routers or media converters that support 1000BASE‑BX‑U modules. Ensure the host device supports single‑fiber BX‑U operation and, if required, enable DDM/DOM in the device management interface to access real‑time diagnostics such as optical power, temperature and supply voltage. Use an LC simplex single‑mode patch cord to connect the transceiver to the remote transceiver or patch panel, matching the required transmit and receive wavelengths for bi‑directional operation. Follow standard hot‑plug procedures and observe ESD precautions during handling.

Recommendations

To achieve optimal link performance, pair this transceiver with compatible single‑mode LC simplex fiber cabling and verify host compatibility for 1000BASE‑BX‑U. If remote diagnostics are important, confirm the network device supports DDM/DOM and monitor the reported parameters periodically. For installations in confined or high‑temperature spaces, verify the host equipment’s environmental specifications to ensure reliable operation.
