The BlueOptics QSFP-40G-SR4-HU-BO is a fiber optic transceiver module with a maximum data transfer rate of 40 Mbit/s and operates at 850 nm. It features a QSFP interface and is made of metal housing, ensuring durability. With a mean time between failures (MTBF) of 1,000,000 hours, it provides reliable performance. The module operates at an input voltage of 3.3 V and weighs 20 g, making it a compact solution for high-speed data transmission.

## Long description

The BlueOptics QSFP-40G-SR4-HU-BO is a QSFP fiber optic transceiver module designed for short-range multimode links. It supports a maximum data transfer rate of 40 Mbit/s over 850 nm optical wavelengths, uses an MPO/MTP connector and comes in a metal housing. The module has an input voltage of 3.3 V, a compact weight of about 20 g, and an MTBF of approximately 1,000,000 hours, offering a durable option for high-speed optical interconnects in data center and networking equipment.
Advantages
The module follows QSFP and MSA standards for electrical, mechanical and functional interoperability and is compatible with hardware platforms that support the original QSFP-40G-SR4 form factor. Metal housing and component selection contribute to a long operational lifetime and thermal stability. Integrated digital diagnostics (DDM/DOM, MSA SFF-8472 compliant) enables real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature to simplify maintenance and troubleshooting.
Suitable for
40G Ethernet links over multimode fiber in data centers
High-speed interconnects between switches, routers and storage systems
Short-reach optical aggregation and spine-leaf connections up to typical multimode distances
Environments requiring digital diagnostics for link monitoring

How to use
Ensure the host device supports QSFP-40G-SR4 modules and that any required firmware or software accepts third-party transceivers. Install the transceiver into a compatible QSFP port according to the host vendor’s hot-plug and electrostatic discharge (ESD) procedures. Connect an MPO/MTP multimode fiber patch cord to the transceiver and verify link status via the host or the module’s digital diagnostics. Use appropriate multimode fiber (OM3/OM4 as recommended by your network design) and verify polarity and fiber routing for parallel MPO/MTP connections.
Usage recommendations
Use this QSFP transceiver in well-ventilated equipment racks and follow manufacturer guidelines for maximum link distances on multimode fiber. Verify DDM/DOM support on the host to access diagnostic parameters, and perform compatibility testing in your environment before large-scale deployment.
