Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber signal transmission, in particular to an optical fiber signal transmission device. Background Art

[0002] Fiber optic transceiver is a type of fiber optic signal transmission device. Fiber optic transceiver is the receiving end device in the fiber optic communication system. It is used to receive optical signals transmitted through optical fibers and convert them into electrical signals for further processing or transmission. Fiber optic transceivers are usually composed of photodetectors, amplifiers, filters, etc., and can be used to receive different types of fiber optic signals, such as single-mode fiber optic signals, multi-mode fiber optic signals, WDM signals, etc. They are generally used in actual network environments where Ethernet cables cannot cover and optical fibers must be used to extend the transmission distance. At the same time, they also play a huge role in helping to connect the last kilometer of optical fiber lines to the metropolitan area network and outer networks. Fiber optic transceivers are the same as general switches. After power is turned on, they can be used by plugging in. No additional configuration is required. They are equipped with fiber optic optical ports, RJ45 crystal head electrical ports, etc.
