QSFP / QSFP+ ports switches

QSFP / QSFP+ ports

— QSFP and QSFP+ are fiber optic ports. The general advantages of optical fiber over conventional Ethernet cable are longer communication range and insensitivity to electromagnetic interference. Specifically, QSFP or QSFP+ is a development of the original SFP standard; in switches, such connectors typically operate at speeds of 40 Gb / s, the standard assumes speeds up to 112 Gb / s. As for the number of such ports, for all its advantages, fiber optics in network equipment is still used less often than Ethernet. Therefore, a plentiful number of such ports in the switch cannot be found, mainly 2 - 6 ports.
