SFP transceiver module BlueOptics SFP-BXU34-20KM-DL-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-DL-BO is a single-mode fiber SFP transceiver module designed for point-to-point optical links. It supports a maximum data transfer rate of 1250 Mbit/s and is housed in a metal casing with a silver finish. The module is compact and lightweight (approximately 20 g) and is specified with a mean time between failures (MTBF) of 1,000,000 hours, making it suitable for long-distance, high-availability connections up to 20 km when used with appropriate single-mode fiber and LC simplex connectors.

Advantages

The module follows MSA-compliant SFP form-factor standards and provides interoperability with hardware platforms that support compatible 1000BASE-BX-U SFP transceivers. Its metal housing offers mechanical robustness and thermal stability. With an MTBF of 1,000,000 hours and a compact 20 g design, the transceiver delivers consistent optical performance for extended operational periods. The transceiver supports single-mode transmission and is suitable for Ethernet and similar high-speed optical protocols at up to 1.25 Gbit/s over long distances.

How to use

Install the SFP module into a compatible SFP slot on your network device according to the device manufacturer’s insertion procedure. Use an LC simplex single-mode patch cord and ensure the far-end transceiver supports the corresponding BX-U wavelength plan (receive 1310 nm / transmit 1490 nm). Verify link parameters and, if available, enable Digital Diagnostics (DDM/DOM) on the host device to monitor supply voltage, temperature and optical power. Follow standard ESD precautions during handling and avoid exposing the optical interface to dust or direct eye exposure from active fiber ends.

Recommendations

For reliable operation, match the transceiver with single-mode fiber and LC simplex connectors, verify host compatibility with 1000BASE-BX-U modules, and perform link testing after installation. Maintain cleanliness of fiber endfaces and confirm that the device firmware or driver supports third-party SFP modules if required by the host platform.
