Description

Network connector

This creation relates to a network connector with POE functionality, and more particularly to the location setting of power terminals in a network connector.

With the promulgation of the corresponding standard of IEEE 802.3an 10GBASE-T, the application of 10G BASE-T Ethernet standard is rapidly developing. The improvement of technology and the improvement of 6A-type wiring system make the transmission speed 10Gb/s and the transmission distance reach 100m. The wiring system became a reality.

In addition, the traditional Ethernet transmission power supply POE (Power Over Ethernet) can only transmit 15W power supply, and then the developed POE+ can only transmit 30W power supply. More and more devices need high wattage (30W or more) POE to supply power, so the development has been made. UPOE (Universal Power over Ethernet). Recently, due to the popularity of cloud computing, virtual desktop terminals have become popular, and wireless 802.11ac APs will begin mass production in the second half of the year.
