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

The BlueOptics SFP-BXU34-20KM-PS-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 metal and weighing approximately 20 g, the module implements MSA-compliant SFP electrical and mechanical interfaces and provides long-term reliability with an MTBF around 1,000,000 hours. The transceiver uses LC simplex connectivity and supports bi-directional 1000BASE-BX-U transmission with separate transmit and receive wavelengths for single-fiber operation.

Advantages

The module offers a compact, metal-cased SFP form factor that fits standard SFP ports and is suitable for use in switches, routers and storage hardware that accept MSA-compliant SFP optics. With a single-mode design and LC simplex connector, it supports long-reach links up to 20 km while maintaining a 1.25 Gbit/s protocol level for Ethernet and related high-speed applications. Built to industry standards, the transceiver includes digital diagnostics monitoring (DDM) support when the host hardware exposes that functionality, enabling remote monitoring of key parameters.

How to use

Insert the BlueOptics SFP-BXU34-20KM-PS-BO into any compatible SFP port while the host device is powered according to the vendor's hot-plug guidance. Connect an appropriate LC simplex single-mode patch cable and ensure the opposite end uses the matching paired transceiver for BX-U operation (transmit and receive wavelengths must be complementary). Verify link negotiation and speed settings on your network device and enable DDM/DOM monitoring if available in the host to view real-time diagnostics such as supply voltage, optical power and temperature.

Recommendations

Use this transceiver with MSA-compliant SFP ports and single-mode LC simplex cabling. For reliable BX-U single-fiber links, pair the module with the complementary wavelength transceiver on the far end and ensure fiber routing and connectors are clean. Confirm that the host device supports DDM/DOM to take advantage of diagnostics and perform compatibility testing in the intended hardware platform before large-scale deployment.
