It came into use in 1999 and has replaced in wired local networks due to its considerable speed improvement over Fast Ethernet, as well as its use of cables and equipment that are widely available, e. A gigabit port can push 1Gbps in each direction, and full-duplex means it can do both directions at the same time - that's 2Gbps of "capacity" according to Mikrotik, or "throughput" according to Arista. Also termed as backplane bandwidth and switching bandwidth is the maximum quantity of data that can be passed between the switch interface processor and the data bus in the switching device. The total data exchange capability of a switch is represented by the backplane bandwidth, which is measured. It connects access layer devices and uplinks from desktop switches or directly to end devices. A standard Ethernet cable (Cat5/5e/6/6a cable) is often used when connecting two RJ45 ports on Gigabit switches. The UniFi Switch is a fully managed, PoE+ Gigabit switch, delivering robust performance and intelligent switching for growing networks. "Optimal conditions" usually means that packets are flowing in one port and out another, there are no corrupted or malformed packets, and that the packets are large enough.
