Ethernet PHY Introduction
Ethernet fiber optic transceiver is a two-way transparent converter that provides Ethernet data signal to fiber optic data signal, which can transmit Ethernet signal through fiber optic line to break the transmission distance limit of 100 meters, making the Ethernet network coverage greatly extended. Fiber optic data communication has the characteristics of long communication distance, large communication data capacity, and is not susceptible to interference.
The application of fiber optics has penetrated into all walks of life at all levels. As the original network systems are based on cable communication, the emergence of fiber optic transceivers to ensure that the electrical signal and fiber optic signal can be smoothly converted to each other, suitable for telecommunications, broadcasting, broadband networks, and other Ethernet environments that require high speed, high data traffic and high performance, high reliability.
Fiber Optic Transceiver
PHY is the physical interface transceiver, which implements the physical layer. the IEEE-802.3 standard defines the Ethernet PHY. it conforms to the specifications in IEEE-802.3k for 10BaseT (Clause 14) and 100BaseTX (Clauses 24 and 25).
The Ethernet PHY and MAC correspond to the two layers of the OSI model - the physical layer and the data link layer. The physical layer defines the electrical and optical signals, line states, clock references, data encoding, and circuitry required for data transmission and reception, and provides standard interfaces (RGMII/GMII/MII) to data link layer devices. The data link layer provides the addressing mechanism, the construction of data frames, data error checking, transmission control, and the standard data interface to the network layer.
Prospects & Applications
With the development of fiber optic technology and fiber optic network skeleton type of comprehensive deployment of the initial formation, fiber optic has become a variety of data communications the most reliable and the best way to communicate. People are beginning to put the original industrial data communication equipment through the optical fiber to group the network. There are many types of industrial data interfaces, such as RS232 serial, RS485 serial, RS422 serial, Ethernet, USB, and CAN bus interfaces.
With the continuous development of industrial data communication, there is a growing need to achieve a unified interface with the fiber optic channel. Ethernet fiber-optic transceivers break the hundred-meter limitation of Ethernet cables in data transmission, relying on high-performance switching chips and large-capacity caches to achieve truly non-blocking transmission switching performance while also providing functions such as balancing traffic, isolating conflicts, and detecting errors to ensure high security and stability during data transmission. Therefore for a long time, fiber optic transceiver products will remain an indispensable part of the actual network set-up.
It is believed that the future of the fiber optic transceiver will continue to develop in the direction of high intelligence, high stability, manageability, and low cost.
Fiber optic technology is used in telecommunications, power communications, mine monitoring, intelligent transportation, automation systems, etc.
