The BlueOptics QSFP-40G-SR4-SS-BO transceiver is a QSFP+ optical module designed for 40 Gbps connections, compatible with the 40GBASE-SR4 standard. It operates at a wavelength of 850 nm over multimode fiber (MMF) using an MTP (MPO) fiber connector and supports a range of up to 150 meters.

The module is hot-pluggable and intended for data center applications, high-speed switch upgrades, aggregation, and spine-leaf architectures.
