The physical layer of the OSI network architecture is where the Ethernet PHY functions. It carries out the Ethernet’s physical layer implementation. Its function is to physically access the link for analogue signals. It is typically connected to a MAC chip in a microcontroller or similar device that handles the higher layer operations via a media-independent interface.
A chip called the Ethernet PHY, which interfaces between the analogue domain of Ethernet’s line modulation and the digital domain of link-layer packet signalling, accomplishes the hardware transmit and receive function of Ethernet frames.
MAC addressing is typically not handled by the PHY because the link layer is in charge of that. The network interface card, which may contain PHY, MAC, and other capabilities integrated into one chip or as separate chips, is where Wake-on-LAN and Boot ROM functionality is implemented.
Fiber or two to four copper pairs are typical Ethernet connections for data transmission. However, a new interface known as Single Pair Ethernet is now available and can make use of just a single pair of copper wires while still communicating at the desired rates. The term “gigabit Ethernet” in computer networking refers to the transmission of Ethernet frames at a rate of one gigabit per second.
The IEEE 8023ab standard specifies 1000BASE-T, the most widely used form. Due to its significant performance gain over Fast Ethernet, as well as its ability to support more devices, has supplanted Fast Ethernet in wired local networks.as well as the utilisation of inexpensive, widely accessible, and comparable to earlier standards cables and equipment.
The OSI model’s physical layer operations must be implemented in a network interface controller by a PHY, which stands for “physical layer” and refers to an electrical circuit that is often implemented as an integrated circuit.
A PHY attaches a link layer device to a physical medium, like copper cable or optical fibre. Physical coding sublayer and physical media dependent layer functionality are frequently present in PHY devices.
Moreover, the suffix -PHY can be used to create a short name that refers to a particular physical layer protocol, such as M-PHY. A PHY chip is complemented with modular transceivers for fiber-optic communication, which together make up the PMD sublayer.
