SFP transceiver module BlueOptics H-BX40-SFP/A-U-BO 1250 Mbit/s

The BlueOptics H-BX40-SFP/A-U-BO 1250 Mbit/s is a compact SFP fiber optic transceiver module designed for single‑mode optical links. Housed in a metal casing and operating from a 3.3 V input, this SFP module supports a maximum data transfer rate of 1250 Mbit/s and is intended for integration into network equipment that accepts SFP form factor modules. The module is silver in colour and weighs approximately 20 g, making it suitable for dense rack deployments and inline replacements where space and weight are factors.

Advantages

The module offers a standardized SFP interface that ensures mechanical and electrical compatibility with SFP slots in switches, routers, storage systems and other networking devices. Its metal housing provides mechanical robustness and thermal dissipation. With a 1250 Mbit/s line rate and low-voltage 3.3 V operation, the transceiver is suitable for common Gigabit and 1.25G optical applications while maintaining a small footprint and lightweight design.

How to use

Ensure the host device supports SFP modules and that firmware or software does not restrict third‑party transceivers. With power off or hot‑swap support as specified by the host, insert the SFP transceiver into an available SFP slot until it seats firmly. Connect the singlemode LC fibre connector to the module’s optical port taking care to match transmit and receive ends of the link. Power on the equipment and verify link status through the device management interface or LED indicators. If required, confirm link speed and diagnostics via the host device’s interface tools.

Recommendations

Handle the transceiver by its housing, avoid touching the optical connector endfaces, and keep protective dust caps in place when not in use. Use only clean, compatible singlemode fiber patch cords and verify connector polarity. For reliable operation, operate the module within the host vendor’s environmental and power specifications and follow recommended ESD precautions during installation.
