Background
In the "dual gigabit" era, networks have increasingly high requirements for rate, increasingly stringent requirements for network reliability, and full network coverage. For connection between a switch and an AP (access point) or other remote modules, a conventional solution is to use twisted pair, so that data transmission can be completed, and PoE (power over ethernet, active ethernet) power supply of the AP can also be completed.
However, with the evolution of Wi-Fi technology, the Wi-Fi 6 standard, which is currently being commercially used on a large scale, requires that the bandwidth of the cable between the switch and the AP be up to 10Gbit/s. Future Wi-Fi 7 standards require that the bandwidth of this cable be up to 40Gbit/s. In terms of PoE power supply, the installation environment of many APs is relatively complex, often requiring PoE power over 100 meters, e.g. 300 meters or even longer for certain stadium APs. If the twisted pair is continuously used, the bottleneck is basically formed after the bandwidth is increased to 10Gbit/s, and after the bandwidth reaches 25Gbit/s, the transmission distance is only 30 meters, so that most PoE power supply scenes can not be met. Thus, there is a need for a cable that enables both high speed data transmission and long-range PoE power.
