QSFP transceiver module BlueOptics QSFP-40G-SR-BD-HU-BO 40000 Mbit/s

The BlueOptics QSFP-40G-SR-BD-HU-BO is a QSFP fiber optic transceiver module for 40GBASE-SR2 bidirectional links. It supports a maximum data rate of 40000 Mbit/s over multimode fiber using LC duplex connectors and is designed for short-range links up to 100 m. The module implements laser-based transmit and receive channels in the 832–918 nm range and follows QSFP MSA electrical and mechanical form-factor conventions for interoperability with compatible network equipment.

Advantages

This BlueOptics QSFP module provides high-speed 40 Gbit/s data transfer in a compact, lightweight silver housing (approx. 40 g). It supports bidirectional transmission on a single pair of multimode fibers, reducing fiber count compared with parallel solutions. The module is manufactured to MSA-compliant mechanical and electrical specifications, includes digital diagnostics monitoring (DDM/DOM) for real-time status (voltage, laser current, output and input power, temperature) and is tested for compatibility with equipment families that accept similar QSFP-40G-SR-BD form-factor transceivers.

Key specifications

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or optical line card while the host device is powered according to vendor guidelines. Connect LC duplex multimode patch cords to the module; observe correct fiber polarity for bidirectional single-pair operation. Verify link negotiation and monitor device status via the host system and the transceiver's DDM/DOM registers if supported by the platform. Follow equipment vendor instructions for hot-plugging and for firmware or driver requirements to ensure the transceiver is recognized and operates at full 40G speed.

Recommendations

Use high-quality OM3/OM4 multimode fiber patch cords and maintain clean LC connectors to ensure optimal optical power and link stability. Confirm that the target hardware explicitly supports MSA-compliant QSFP bidirectional SR2 transceivers and enables DDM/DOM access if you plan to use monitoring and diagnostic features.
