BlueOptics SFP-BXU35-40KM-SS-BO network transceiver module Fiber optic 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-SS-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑BX‑U applications with a maximum data rate of 1250 Mbit/s. The module has a metal housing, LC simplex interface and a compact SFP form factor. It supports long‑distance links up to 40 km over single‑mode fiber and includes Digital Diagnostic Monitoring (DDM) capabilities where supported by the host device.

Advantages

The transceiver offers an industry‑standard SFP interface for easy hot‑plug installation and interoperability with MSA‑compliant equipment. Its metal housing and a rated MTBF of 1,000,000 hours provide mechanical robustness and long operational life. With support for 1000BASE‑BX‑U signalling and LC simplex connectors, the module enables simultaneous transmit and receive on separate wavelengths optimized for long‑reach single‑mode transmission.

How to use

Insert the BlueOptics SFP‑BXU35‑40KM‑SS‑BO into an empty SFP cage on a compatible switch, router or media converter while the host device is powered according to the vendor’s instructions. Use an appropriate single‑mode LC patch cable to connect to the remote transceiver, ensuring correct orientation for LC simplex connections and matching the required bi‑directional wavelengths on each end. Verify link status through the host device interface and enable DDM/DOM monitoring if the platform supports it.

Recommendations

Confirm host compatibility with 1000BASE‑BX‑U SFP modules and ensure fiber patch cords and splices meet single‑mode specifications. For reliable long‑reach performance, use low‑loss connectors and maintain proper cleaning procedures for fiber endfaces. If link diagnostics are required, enable DDM/DOM in the host and monitor real‑time parameters such as optical power and temperature.
