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

The BlueOptics QSFP-40G-SR-BD-AL-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s optical data links over multimode fiber. Housed in a metal enclosure and weighing approximately 40 g, the module implements a QSFP interface and supports bidirectional 40GBASE-SR2-BIDI operation with LC duplex connectors according to MSA standards. With an MTBF specified around 1,000,000 hours, it is intended for integration into switches, routers, storage systems and other network hardware that support QSFP 40G optical transceivers.

Advantages

The module provides a compact QSFP form factor with bidirectional transmission on a single multimode fiber pair, enabling up to 40 Gbit/s throughput while reducing cabling complexity. Constructed with a durable metal housing, it offers mechanical stability and thermal performance suitable for rack-mounted network equipment. The transceiver includes digital diagnostics monitoring (DDM/DOM) capabilities in line with SFF-8472 for real-time monitoring of supply voltage, laser bias current, transmit and receive power, and temperature when supported by host hardware. Manufacturing follows MSA guidelines and uses industry-grade components to ensure interoperability and extended operational lifetime.

How to use

Install the BlueOptics QSFP-40G-SR-BD-AL-BO into a compatible QSFP slot on your network device following the device manufacturer's hot-plug guidelines. Use LC duplex multimode fiber patch cords and ensure correct orientation for bidirectional (BIDI) pairs. Verify that the host hardware and firmware support 40GBASE-SR2-BIDI transceivers and, if required, enable or check DDM/DOM monitoring in the management interface to read real-time diagnostic values. Perform link testing after installation to confirm signal levels and expected throughput.

Recommendations

Use high-quality multimode fiber patch cords and maintain clean LC connectors to ensure low insertion loss. Match the transceiver to compatible hardware that supports QSFP 40GBASE-SR2-BIDI modules and confirm firmware compatibility for DDM/DOM functions. For reliable operation, avoid excessive mechanical stress on the module and adhere to the host device’s environmental specifications.
