SFP transceiver modul BlueOptics SFP-BXU34-20KM-NG-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-NG-BO is a single-mode fiber SFP transceiver module designed for up to 1250 Mbit/s data rate and point-to-point links of up to 20 km. The module is built in a metal housing, weighs approximately 20 g and implements LC simplex connectivity. It supports 1000BASE-BX-U operation with a transmitting wavelength around 1490 nm and receiving wavelength around 1310 nm, and includes Digital Diagnostics Monitoring (DDM) for real-time status of key optical parameters. The product follows MSA SFP mechanical and electrical standards to ensure interoperability with compatible network hardware.

Advantages

The transceiver offers a compact SFP form factor and metal housing for mechanical stability and thermal dissipation. With a rated MTBF of 1,000,000 hours and the use of proven optical and IC components, it provides long operational availability for carrier and enterprise networks. The integrated DDM/DOM support simplifies monitoring and maintenance by reporting supply voltage, laser bias current, output power, received power and temperature when supported by the host device.

How to use

Install the SFP transceiver into a compatible SFP port on your switch, router or other network device while the host device is powered according to the vendor instructions. Connect a single-mode LC simplex patch cable between this transceiver and the corresponding remote transceiver; ensure correct orientation for the BX-U (bidirectional) link so that the Tx wavelength on one end matches the Rx wavelength on the other end. Verify link status and, if available, read DDM parameters through the host device management interface to confirm optical power levels and temperature within expected ranges.

Recommendations

Use factory-quality single-mode patch cords and follow fiber handling best practices (avoid tight bends, keep connectors clean). Confirm host device compatibility with 1000BASE-BX-U SFP modules and enable DDM/DOM support in the management interface if remote diagnostics are required. For critical links, test the module in your specific hardware prior to deployment to validate interoperability and link budget.
