SFP transceiver module BlueOptics SFP-BXU35-20KM-NG-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-20KM-NG-BO is a Small Form-factor Pluggable (SFP) fiber optic transceiver designed for single-mode links with a maximum data transfer rate of 1250 Mbit/s. The module comes in a metal housing with a silver finish, weighs approximately 20 g, and is built to provide long operational life with an MTBF of 1,000,000 hours. It implements the 1000BASE-BX-U duplex-over-single-fiber transmission scheme using LC simplex connectivity and supports simultaneous transmit and receive channels on separate wavelengths (typical for BX-U operation).

Advantages

The transceiver offers a compact SFP form factor that is compatible with MSA-compliant SFP ports and common networking equipment that support 1000BASE-BX-U. Its metal housing contributes to mechanical durability and electromagnetic shielding while the lightweight construction facilitates easy handling and slot installation. With an MTBF of 1,000,000 hours and support for a 20 km reach on single-mode fiber, the module is suitable for long-term deployment in LAN and metro-edge applications. The unit also supports digital diagnostic monitoring when implemented by host hardware, aiding remote monitoring of link parameters.

How to use

Install the BlueOptics SFP-BXU35-20KM-NG-BO into any compatible SFP slot while the host device is powered on or off according to the device manual; the module is hot-pluggable. Connect an LC simplex single-mode patch cord to the transceiver and the corresponding remote transceiver, observing correct orientation for transmit and receive fibers. Ensure the host device supports 1000BASE-BX-U and, if desired, that digital diagnostic monitoring (DDM/DOM) is enabled and supported by the hardware to read link parameters. Check link status indicators on the host device to verify successful negotiation and data transmission.

Recommendations

For reliable operation, use single-mode fiber and LC simplex patch cords rated for the intended link distance, keep connectors clean and protected, and follow the host equipment vendor’s guidelines for module compatibility and firmware support. If remote monitoring is required, confirm DDM/DOM support in the host platform before deployment.
