## Summary description

The BlueOptics QSFP-40G-SR4-PT-BO is a QSFP transceiver module designed for high-speed data transfer at 40 Mbit/s over fiber optics. It operates at a wavelength of 850 nm and has a robust metal housing. With a mean time between failures of 1,000,000 hours, it ensures reliability. The module requires a 3.3 V input voltage and weighs only 20 g, making it suitable for various networking applications.

## Long description

The BlueOptics QSFP-40G-SR4-PT-BO is a QSFP transceiver module for 40 Mbit/s short-range multimode fiber links. It operates at an 850 nm wavelength, uses an MPO/MTP connector, and is housed in a robust metal casing. The module requires a 3.3 V input and weighs approximately 20 g. Designed to meet MSA QSFP standards and with a high MTBF, it supports common high-speed protocols and provides diagnostic monitoring for easier maintenance.
Advantages
The transceiver provides a standardized QSFP form factor with MPO/MTP connectivity for four-lane 40 Mbit/s operation over multimode fiber, enabling compact, high-density installations. Metal housing ensures mechanical stability and thermal dissipation, while a mean time between failures (MTBF) rating indicates long-term reliability. Digital diagnostics (DDM/DOM) support remote monitoring of voltage, temperature, laser bias and optical power, simplifying troubleshooting and preventive maintenance.
Suitable for
40 Mbit/s short-range links in data centers and network aggregation points
Interconnects between switches, routers and storage systems that accept QSFP modules
High-density rack deployments requiring MPO/MTP multimode fibre connections
Environments where remote optical diagnostics improve uptime and maintenance
Key specifications

How to use
Insert the QSFP-40G-SR4-PT-BO module into a compatible QSFP port following the host equipment manufacturer’s hot-plug guidance. Connect an MPO/MTP multimode fiber patch cord to the module’s connector, ensuring correct fiber polarity and that the fiber type and connector version match system requirements. Verify that the host device recognizes the module and, if available, enable or read out the digital diagnostics to check supply voltage, temperature, laser bias current and optical power. Observe standard ESD precautions and handle the transceiver by its housing to avoid contamination of optical interfaces.
Usage recommendations
Use OM3/OM4 multimode fiber for optimal reach and performance at 850 nm, maintain clean connector endfaces, and confirm host compatibility with QSFP-40G-SR4-PT-BO modules. Enable digital diagnostics where supported to monitor link health and simplify maintenance procedures.
