SFP transceiver module BlueOptics SFP-BXU35-40KM-CI-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-CI-BO is a single‑mode fiber optic SFP transceiver module designed for up to 1250 Mbit/s data rate. The module has a metal housing, a compact SFP form factor with LC simplex optical connector and a weight of approximately 20 g. It implements a bi‑directional 1000BASE‑BX‑U link using separate transmit and receive wavelengths (typ. 1550 nm transmit / 1310 nm receive) to support point‑to‑point links up to 40 km over single‑mode fiber. The transceiver supports digital diagnostic monitoring (DDM/DOM) and is manufactured to MSA‑compliant mechanical and electrical specifications for broad interoperability.

Advantages

The module offers reliable long‑reach connectivity in a compact SFP package, a metal housing for mechanical stability and an MTBF of around 1,000,000 hours for extended operational life. Compliance with MSA standards ensures compatibility with major vendor platforms that accept equivalent 1000BASE‑BX‑U SFPs. The transceiver supports DDM for real‑time monitoring of parameters such as optical power and temperature, which simplifies maintenance and troubleshooting.

How to use

Insert the SFP module into a compatible SFP port while the host device is powered down or following the vendor’s hot‑swap procedure. Connect an LC simplex single‑mode patch cable between this transceiver and the remote transceiver, taking care to match the BX wavelengths and pairing (transmit of one end connects to receive of the other end). Verify link establishment and check DDM readings via the host system to confirm optical power, temperature and voltage parameters. Follow the equipment vendor’s instructions for firmware or software settings if the platform requires specific transceiver configuration.

Recommendations

Use quality single‑mode LC simplex cabling, ensure fiber connectors are clean before mating, and confirm that the host hardware supports 1000BASE‑BX‑U SFP modules and DDM if diagnostic functions are required. For long links, validate link budget and attenuation to ensure reliable operation up to 40 km.
