SFP transceiver module BlueOptics SFP-BXU34-40KM-NK-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-NK-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U links with a maximum data transfer rate of 1250 Mbit/s. The transceiver features an LC simplex connector, operates with a transmitter wavelength of 1490 nm and a receiver wavelength of 1310 nm, and supports point-to-point links up to 40 km. Its metal housing and compact SFP form factor make it suitable for insertion into standard SFP slots on switches, routers and other network equipment that support MSA-compliant SFP modules.

Advantages

The module offers Digital Diagnostics Monitoring (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature, simplifying maintenance and fault analysis. With an MTBF of around 1,000,000 hours and a lightweight metal enclosure, the transceiver provides long service life and mechanical robustness. Compliance with SFP MSA standards ensures interoperability with a wide range of hardware platforms that accept compatible 1000BASE-BX-U SFP modules.

How to use

Install the BlueOptics SFP-BXU34-40KM-NK-BO by inserting the module into an empty SFP port on compatible networking equipment until it latches. Connect a single-mode LC simplex fiber patch cable between this transceiver and the corresponding remote transceiver, ensuring correct polarity for the BX-U (wavelength-specific) configuration so that the 1490 nm transmitter aligns with the remote receiver and the 1310 nm receiver aligns with the remote transmitter. Verify link status via the host device interface and, if supported, enable DDM/DOM monitoring to check operational parameters remotely.

Recommendations

Use high-quality single-mode fiber patch cords and, if possible, patch panels or adapters rated for LC simplex connections to achieve the specified 40 km range. Ensure the host device firmware or driver supports third-party SFP modules and DDM/DOM if remote diagnostics are required. Avoid bending the fiber beyond recommended radii and follow ESD precautions when handling the transceiver.
