With the continuous extension of network technology and application scenarios, structured cabling systems are also developing. However, the value of all technologies cannot be separated from practical applications, especially cabling technology. Over the past decade, Category 5e and Category 6 systems have long occupied the mainstream market for building cabling. With the rapid deployment of mobile 5G, the vigorous development of the Internet of Things, digital office, travel and life are constantly changing people's original habits; thus, higher requirements are put forward for the network system of smart buildings. Cat.6A cabling systems gradually replace Cat.5e and occupy the mainstream market for smart building cabling.
