ETHERNET COMMUNICATION SYSTEM TRANSMITTED OVER A PAIR OF TWISTED PAIRS OR TWO PAIRS OF TWISTED PAIRS

摘要

The present invention discloses an Ethernet communication system that is transmitted only through two pairs of twisted pairs. The Ethernet communication system includes one first transceiver and two pairs of Egg Zekley twisted pairs, and the first transceiver includes one first physical coding sublayer (PCS) and the first physical coding sublayer. And two first physical medium attachments (PMAs) connected to the layer and two first hybrid circuits each connected to the two first physical media connections. The two pairs of EGJekley twisted pairs are respectively connected to the two first hybrid circuits of the first transceiver.
