Description

The Q-SFP-40G-SR4 is a hot-pluggable QSFP+ optical transceiver designed for 40-Gigabit Ethernet applications over multimode fiber. It supports an aggregate data rate of up to 41.25 Gb/s using four parallel 10 Gb/s lanes. The module uses 850 nm VCSEL transmitters and PIN receivers and connects through a single MPO-12 optical interface. Transmission distances reach 100 m on OM3 multimode fiber and 150 m on OM4 multimode fiber, making it ideal for high-speed data center networking and short-range optical links.
