SFP-transceivermodule BlueOptics SFP-BXU35-40KM-IX-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-IX-BO is a single-mode fiber optic SFP transceiver designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. The module has a metal housing, a silver finish and a compact SFP form factor. It supports LC simplex connections and is intended for point-to-point fiber links up to 40 km when used with appropriate single-mode fiber. The transceiver implements transmitter and receiver wavelengths for asymmetric single-fiber operation and provides Digital Diagnostics Monitoring (DDM/DOM) support when the host system exposes that functionality.

Advantages

The module offers an industry-standard SFP interface and a metal housing for mechanical robustness and EMI resistance. With a low weight of approximately 20 g and an MTBF rated at 1,000,000 hours, it is suitable for installations that require long-term availability and minimal maintenance. Compliance with MSA electrical and mechanical specifications ensures broad interoperability with network equipment that accepts SFP transceivers.

How to use

Install the transceiver into a compatible SFP port on your network device until it seats firmly. Connect an LC simplex single-mode fiber patch cable with correct polarity to the LC connector. Configure the device for 1000BASE-BX-U operation if required by the platform and check link status through the host device management interface. If DDM/DOM data is needed, enable or access diagnostics on the host system to monitor parameters such as input/output power, bias current and temperature.

Recommendations

Ensure the host equipment officially supports BX-U type SFPs and DDM/DOM if you plan to use monitoring features. Use quality single-mode fiber and properly rated patch cords to achieve the specified 40 km range, and verify link budgets for your installation. Handle the transceiver by its edges, keep dust caps on unused connectors, and avoid exposing the optical port to contamination to maintain performance and reliability.
