Módulo transceptor SFP BlueOptics SFP-BXU34-20KM-SO-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-SO-BO is an SFP fiber optic transceiver module designed for single-mode links with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal case and weighing approximately 20 g, the module supports long-distance optical transmission up to 20 km using an LC simplex connector. It implements a bidirectional 1000BASE-BX-U configuration with separate transmit and receive wavelengths for efficient single-fibre operation and includes Digital Diagnostics Monitoring (DDM/DOM) support for real-time link monitoring when the host hardware provides that feature.

Advantages

The module offers MSA-compliant form factor and electrical interfaces for broad interoperability with equipment that supports 1000BASE-BX-U SFP transceivers. A metal housing improves mechanical robustness and thermal characteristics while an MTBF around 1,000,000 hours indicates an extended operational lifetime for reduced maintenance. Digital diagnostics provide live parameters such as supply voltage, laser bias current, output and input power and temperature to ease remote troubleshooting and preventive maintenance.

How to use

Install the BlueOptics SFP-BXU34-20KM-SO-BO into an available SFP port of a compatible switch, router or storage device while the host is powered down or following hot-plug guidance from the equipment vendor. Connect a single-mode LC simplex patch cable between this transceiver and the corresponding remote transceiver; ensure the remote end uses the complementary wavelength configuration for bidirectional operation. If available, enable or verify DDM/DOM in the host management interface to read real-time diagnostic values. Follow your network equipment vendor's instructions for interface configuration, speed/duplex settings and link validation.

Recommendations

Use high-quality single-mode fibre patch cords and ensure proper cleaning of LC connectors to maintain optimal signal levels. Verify that the target hardware explicitly supports 1000BASE-BX-U or compatible SFP modules and confirm DDM/DOM compatibility if remote diagnostics are required. For long-term reliability, operate the transceiver within the host's specified temperature range and avoid excessive mechanical stress on the fibre connections.
