Netgear 49Y7884 Compatible 40GBASE-SR4 QSFP+ 40G 850nm 100m DOM MTP/MPO-12 UPC MMF Ethernet Optical Transceiver Module
The 40G-QSFP-SR4 transceiver is a high-performance, parallel 40Gb/s QSFP+ optical module designed for high-speed data transmission. It integrates four independent transmitters and receivers, utilizing a four-channel 850nm VCSEL array, PIN array, amplifier, and driver to achieve compact size, low power consumption, and cost efficiency. Each channel supports data rates of up to 10Gbps, enabling transmission distances of up to 100 meters over OM3 multimode fiber. This makes the module ideal for high-density, short-range applications such as data center interconnects and high-performance computing.

No need for vendor-specific coding or configuration tools. These just worked out of the box, even in slightly older switches.
