Fiber optic transceiver: the device is equipped with optical and electrical ports on both ends, the optical port is connected to the optical fiber, the electrical port is connected to the Ethernet cable, the use of Ethernet cables to dock switches, routers, computers and other. Fiber optic transceiver: the device is equipped with optical and electrical ports on both ends, the optical port is connected to the optical fiber, the electrical port is connected to the Ethernet cable, the use of Ethernet cables to dock switches, routers, computers and other. Optical port is the abbreviation of optical fiber interface. Fiber optic connectors connect optical fibers and can be connected and disconnected faster than splicing. Since Ethernet transmission over UTP cables is generally limited to distances of. The answer is no, because the performance of the electrical port module is no less than that of the optical port module, but also has unique advantages. The electrical signal is converted into an optical signal through the transmitting end of the optical module, and then converted into an electrical signal through the receiving end. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications.
