SFP transceiver module BlueOptics H-BX20-SFP/A-U-BO 1250 Mbit/s

The BlueOptics H-BX20-SFP/A-U-BO is an SFP transceiver module designed for single-fiber optical links with a maximum data transfer rate of 1250 Mbit/s. The module uses an LC Simplex interface and implements a bi-directional 1000BASE-BX-U topology: it transmits at 1310 nm and receives at 1490 nm. The transceiver is built to MSA-compliant dimensions and electrical/optical interfaces, weighs approximately 20 g and is finished in silver. With a mean time between failures (MTBF) of 3,000,000 hours, the module targets continuous operation in common network hardware platforms that accept SFP form-factor transceivers.

Advantages

The H-BX20-SFP/A-U-BO offers a compact SFP form factor compatible with many switches, routers and storage systems that support 1000BASE-BX-U modules. Its LC Simplex connector and bi-directional transmit/receive wavelengths enable single-fiber deployments where separate transmit and receive strands are not available. The module conforms to MSA standards for mechanical and optical compatibility and includes digital diagnostics monitoring (DDM/DOM) functionality for real-time reporting of supply voltage, laser bias current, transmit power, receive power and temperature. Built using components from established optical and IC manufacturers, the transceiver is intended for long operational life and stable optical performance.

Suitable for

• Single-fiber point-to-point links using 1000BASE-BX-U

How to use

Install the H-BX20-SFP/A-U-BO by inserting the SFP module into an available SFP port on compatible network equipment until it latches. Connect an LC Simplex fiber patch cable with the appropriate polarity to the transceiver’s LC connector. Ensure the remote transceiver uses the complementary BX wavelength pairing (transmit/receive) for single-fiber operation. Verify that the host device supports 1000BASE-BX-U and, if required, enable DDM/DOM monitoring in the equipment management interface to read real-time diagnostic values. Power the equipment and confirm link status and data throughput through the device’s port indicators or management console.

Usage recommendations

Use high-quality single-mode fiber and LC Simplex patch cables matched to the transceiver’s wavelength plan to achieve expected range and power margins. Verify compatibility with the specific network hardware vendor and platform; when remote diagnostics are needed, ensure the host system supports DDM/DOM to access diagnostic parameters. Observe ESD precautions when handling the SFP module and keep dust caps on connectors until connection to minimize contamination.
