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

The BlueOptics SFP-BXU35-40KM-MT-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications with a data rate of up to 1250 Mbit/s. The module features an LC simplex optical interface, a metal housing in silver, and a compact light-weight design (approx. 20 g). It supports bi-directional operation using separate wavelengths for transmit and receive and is intended for long-reach links up to 40 kilometres, offering stable optical connectivity for switches, routers and other network equipment that accept MSA-compliant SFP modules.

Advantages

The transceiver offers MSA-compliant mechanical and electrical interfaces for broad interoperability and is manufactured to meet industrial quality standards. Its metal housing provides mechanical robustness and thermal stability, while the module’s long mean time between failures (MTBF) supports sustained availability in demanding network environments. The device supports Digital Diagnostics Monitoring (DDM/DOM), enabling remote readout of supply voltage, laser bias current, transmit power, receive power and temperature for easier maintenance and troubleshooting.

Key specifications

How to use

Install the module into any compatible SFP port following the host device manufacturer’s instructions while the device is powered down or hot-plugging if supported. Use single-mode fiber patch cords with LC simplex connectors and ensure correct pairing of transmit and receive ends because the module uses different wavelengths for TX and RX. Verify link status on the host equipment and, if available, enable DDM/DOM monitoring to observe optical parameters and confirm proper operation. Follow standard ESD precautions when handling the transceiver and keep the optical connector caps on when the module is not connected to protect the optical interface.

Recommendations

For optimal performance, pair the transceiver with quality single-mode fiber and LC simplex patch cords, confirm compatibility with the host device firmware, and enable DDM/DOM monitoring for ongoing diagnostics. Store and operate the module within the manufacturer’s recommended temperature and humidity ranges and avoid mechanical stress on the fiber to maintain link quality over the full 40 km range.
