SFP transceiver module BlueOptics SFP-BXU35-20KM-PS-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-20KM-PS-BO is a single-port SFP fiber-optic transceiver designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Housed in a metal enclosure and weighing approximately 20 g, this module is intended for single-mode fiber links with LC simplex connector, supporting unidirectional transmit and receive wavelengths suitable for up to 20 km reach. The module implements industry-standard SFP electrical and mechanical interfaces for compatibility with network switches, routers and storage systems that accept MSA-compliant SFP modules.

Advantages

The module offers stable 1.25 Gbit/s performance over single-mode fiber and a compact SFP form factor that fits a wide range of network devices. A metal housing provides mechanical robustness and thermal stability, while the specified MTBF of 1,000,000 hours indicates long-term reliability for continuous operation. Support for digital diagnostics (DDM/DOM) simplifies monitoring of parameters such as supply voltage, laser power and temperature when the host hardware enables this feature.

How to use

Insert the BlueOptics SFP-BXU35-20KM-PS-BO module into an available SFP slot on the host device while the device is powered on or according to the host vendor's hot-plug recommendations. Connect LC simplex single-mode patch cords to the module’s transmit and receive ports, observing correct fiber polarity and the unidirectional nature of 1000BASE-BX-U links. Ensure the host device is configured for a 1.25 Gbit/s SFP module and that any required firmware or software settings allow third-party transceivers if applicable. If monitoring is required, enable DDM/DOM functions in the host to read diagnostic parameters.

Recommendations

Use factory-tested single-mode LC patch cords and follow proper fiber handling procedures to maintain link quality. Confirm compatibility with the host hardware documentation before deployment and perform link validation tests after installation to verify expected throughput and DDM readings.
