PHY (English: Port physical layer), which can be called port physical layer in Chinese, is a common abbreviation for OSI model physical layer.
PHY connects a data link layer device (MAC) to a physical medium, such as an optical fiber or copper cable. Typical PHY includes PCs (physical coding sublayer) and micro RJ45 network connector PMD (physical media dependent). PCs encodes and decodes the sent and received information. The price of micro RJ45 connector is to make the receiver easier to recover the signal.
PHY is a device that operates the OSI model physical layer of micro communication transformer. A micro network communication transformer Ethernet PHY is a chip that can send and receive Ethernet data frames. Micro RJ45 network connector price it usually lacks the advanced function of Wake-On-LAN or boot ROM provided by NIC (network interface controller) chip. In addition, unlike NICs, PHY does not have its own MAC address.
