SFP transceiver BlueOptics SFP-BXU34-40KM-F5-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-F5-BO is a single‑mode SFP transceiver module designed for long‑distance fiber connections with a maximum data rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, the module supports LC simplex optical connections and is built to industry MSA specifications for interoperability with compatible network hardware. With a high MTBF rating, it is intended for stable point‑to‑point optical links over extended distances.

Advantages

This SFP transceiver offers single‑mode optical transmission with separate transmit and receive wavelengths suitable for bi‑directional links on a single fiber. The metal housing increases mechanical durability and supports reliable heat dissipation. Compliance with MSA standards ensures broad compatibility with equipment that accepts standard SFP modules. A high mean time between failures (MTBF) reflects a design aimed at long service life and reduced maintenance needs.

How to use

Install the transceiver into a compatible SFP slot on your networking device following the device manufacturer's insertion procedure. Connect an LC simplex single‑mode fiber patch cable matching the module's bi‑directional wavelengths to the transmit and receive ports as labeled. Ensure the host device firmware or software supports the desired data rate and, if required, enables digital diagnostic monitoring. Observe standard electrostatic discharge (ESD) precautions during handling and avoid touching the optical interfaces; keep protective dust caps in place until connection.

Recommendations

For optimal link performance, use single‑mode fiber and high‑quality LC simplex patch cords, verify polarity for bi‑directional links, and confirm that the host device supports DDM/DOM if monitoring is needed. Regularly inspect and clean fiber endfaces and ensure firmware compatibility with the transceiver to maintain stable operation over the expected service life.
