SFP transceiver module BlueOptics SFP-BXU34-20KM-IT-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-IT-BO is a single-mode fiber optic SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. Encased in a metal housing and weighing approximately 2 grams, the module supports optical transmission up to 20 km and includes Digital Diagnostic Monitoring (DDM/DOM) functionality for real-time diagnostics of supply voltage, laser bias current, transmit power, receive power and temperature. The module uses an LC simplex connector and operates with separate transmit and receive wavelengths suitable for single-fiber bidirectional links.

Advantages

The transceiver offers long-distance single-mode transmission up to 20 km while maintaining a compact SFP form factor and low weight. A metal housing provides mechanical durability and thermal stability, and built-in DDM enables remote monitoring and simplified troubleshooting. The module is compliant with MSA SFP mechanical and electrical specifications and manufactured to industry standards for predictable interoperability with compatible network equipment.

How to use

Install the SFP transceiver into any compatible SFP slot on switches, routers or optical equipment following the host device manufacturer’s insertion and extraction procedure. Connect an LC simplex single-mode patch cable to the transceiver and ensure the remote end is fitted with the corresponding BX-U transceiver configured for complementary wavelengths. Verify link status and, if available, read diagnostic data through the host device to confirm proper optical power levels, supply voltage and temperature. Observe ESD precautions during handling and avoid touching the optical ferrule.

Recommendations

Use quality single-mode LC patch cords and clean connector end-faces prior to insertion to ensure optimal signal quality. Confirm that the host device supports 1000BASE-BX-U and DDM/DOM if those features are required. For reliable long-term operation, allow adequate ventilation around equipment and follow the vendor’s guidelines for operating temperature and dust control.
