## Summary description

The BlueOptics SFP-BXU35-40KM-CI-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing, weighs 20 g, and has an MTBF of 1,000,000 hours. Ideal for reliable network connections over long distances.

## Long description

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.
Suitable for
Point‑to‑point Ethernet links up to 40 km over single‑mode fiber
Upgrading or replacing 1000BASE‑BX‑U SFP ports in switches, routers and storage equipment
Networks requiring DDM/DOM monitoring for link diagnostics
Environments where a compact SFP transceiver and metal housing are preferred
Key specifications
Form factor: SFP (Small Form‑Factor Pluggable)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Fiber type: single‑mode fiber
Interface/connector: LC simplex
Wavelengths: transmit ~1550 nm / receive ~1310 nm (bi‑di BX‑U operation)
Maximum reach: up to 40 km (typical, depends on fiber and link budget)
Housing: metal
Weight: approx. 0.02 kg
Diagnostic: DDM/DOM support
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.
Usage 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.
