QSFP-transceiver BlueOptics QSFP-40G-SR4-QU-BO 40000 Mbit/s

The BlueOptics QSFP-40G-SR4-QU-BO is a QSFP fiber optic transceiver module engineered for 40 Gbit/s data links over multimode fibre. It uses an MPO/MTP connector and supports 40GBASE-SR4 short-range optical transmission up to 150 m on appropriate multimode fibre. The module has a compact QSFP form factor, a silver housing, weighs approximately 0.02 kg and is intended for use in data center switches, routers and other network devices that accept QSFP 40GBASE-SR4 optics.

Advantages

This transceiver follows MSA QSFP specifications and provides simultaneous transmit and receive capability on parallel multimode fibre using 850 nm optics. Built to be compatible with major hardware platforms that support 40GBASE-SR4 QSFP modules, it offers digital diagnostics support for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature where the host supports DDM/DOM. The small, lightweight metal housing simplifies installation and passive cooling in dense rack environments.

Key specifications

How to use

Install the QSFP transceiver into a compatible QSFP slot on the host device according to the vendor's hot-plug and electrostatic discharge (ESD) procedures. Ensure the device firmware or drivers support third-party QSFP optics and enable DDM/DOM in the host if you require digital diagnostic data. Connect an appropriate MPO/MTP multimode patch cord or harness, observing correct polarity and fibre type (OM3/OM4) to achieve the stated distances. After insertion and connection, verify link status on the host and confirm optical power and diagnostics through the management interface if available.

Recommendations

Use OM3 or OM4 multimode fibre for reliable 40GBASE-SR4 performance up to 150 m, and maintain clean MPO/MTP connector endfaces to avoid signal loss. Confirm host compatibility and, where possible, test the transceiver in your specific hardware and firmware configuration prior to production deployment.
