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

The BlueOptics SFP-BXU35-40KM-SO-BO is an SFP fiber optic transceiver module designed for single-mode links with a maximum data rate of 1250 Mbit/s. The module features a metal housing, a lightweight design of approximately 20 g, and a high MTBF rating of 1,000,000 hours, making it suitable for long-distance optical connections up to 40 km when used with appropriate single-mode fiber and LC Simplex connectors. It supports 1000BASE-BX-U operation with separate transmit and receive wavelengths for point-to-point single-fiber links.

Advantages

The module provides MSA-compliant SFP form factor interoperability and supports Digital Diagnostic Monitoring (DDM/DOM) for real-time monitoring of optical and electrical parameters. Its metal housing contributes to mechanical robustness and EMI shielding, while the low weight and standard SFP interface allow easy hot-plug installation in compatible switches, routers and storage devices. The high MTBF indicates long operational life and reduced maintenance requirements.

How to use

Install the SFP transceiver into a compatible SFP port while the host device is powered on or as allowed by the device vendor for hot-plug operation. Use a single-mode LC simplex fiber patch cable to connect the transceiver to the remote module or patch panel, observing the correct TX/RX orientation for BX-U operation. Ensure the host equipment supports 1000BASE-BX-U and DDM if you require diagnostic monitoring. After insertion, verify link status on the host device and check DDM values if available to confirm proper optical power and operating conditions.

Recommendations

For optimal performance, pair the transceiver with single-mode fiber certified for long-distance links and keep connectors clean. Confirm compatibility with the host hardware and firmware; if diagnostics are required, ensure DDM/DOM is enabled on the system. Store and handle the module following ESD precautions and avoid excessive mechanical stress on the LC connector and fiber.
