is a compact hot-swappable transceiver for data communications applications. The form factor and electrical interface are specified by the Multi-Source Agreement (MSA) under the auspices of the Small Form Factor Committee. It connects network hardware, such as servers and switches, to fiber optic cables or active or passive electrical copper connections. It is an industry format developed and supported by many network component vendors that allow data rates ranging from 4x1 Gb/s for QSFP and 4x10 Gbit/s for QSFP+ to a maximum rate of 4x28 Gbit/s, i.e. QSFP28 for 100 Gbit/s links.
