Módulo transceptor SFP BlueOptics SFP-BXU35-40KM-CS-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-40KM-CS-BO is an SFP fiber optic transceiver module designed for 1000BASE-BX-U single-mode links with a maximum data rate of 1250 Mbit/s. The module uses an LC simplex connector and implements a bi-directional wavelength pair (transmit 1550 nm / receive 1310 nm) to enable duplex transmission over a single fiber for distances up to 40 km. Housed in a metal enclosure and weighing approximately 20 g, the transceiver meets industry MSA form-factor requirements and includes Digital Diagnostics Monitoring (DDM) support for real-time link parameter monitoring where host hardware supports this feature.

Advantages

The module provides a compact SFP form factor compatible with MSA-compliant ports and is suitable for high-availability installations thanks to a reported MTBF of 1,000,000 hours. Its single-mode optical design and LC simplex connector allow long-distance 1000BASE-BX-U operation up to 40 km while maintaining a straightforward plug-and-play interface. Built with a metal housing and DDM support, the transceiver offers physical robustness and remote diagnostic capability for simplified maintenance and monitoring.

How to use

Insert the SFP transceiver into an MSA-compliant SFP slot on compatible network equipment until it clicks into place, then connect an LC simplex single-mode fiber patch cable to the transceiver. Ensure the corresponding remote transceiver is configured for the opposite wavelength direction (the module transmits at 1550 nm and receives at 1310 nm). Verify link status and, if available, read DDM parameters from the host system to monitor supply voltage, laser bias current, transmit power, receive power and module temperature. Follow the equipment vendor guidelines for enabling or disabling any vendor-specific checks or locking mechanisms to ensure compatibility.

Recommendations

Use high-quality single-mode fiber and appropriate LC patch cords rated for long-distance links, keep optical connectors clean, and confirm that the host hardware supports BX-U transceivers and DDM if diagnostic monitoring is required. Observe ESD precautions when handling the module and store unused transceivers in protective packaging to avoid contamination of the optical interface.
