Fiber optic transceiver
Fiber optic transceiver is an Ethernet transmission media conversion unit that exchanges short distance twisted pair electrical signals with long-distance optical signals, and is referred to as an optoelectronic converter in some places. This type of product is generally used in actual network environments where Ethernet cables cannot cover and fiber optic cables must be used to extend transmission distance. It is usually positioned in the access layer of broadband metropolitan area networks and is commonly used to help connect the last mile of fiber optic lines to metropolitan area networks and outer networks.
Fiber optic transceivers are essentially just completing data conversion between different media, which can connect two switches or computers within 0-120km, but in reality, they have more extensions.
Optical transceiver
Optical transceiver is divided into transmitter and receiver, where the transmitter converts electrical signals into optical signals; The receiver converts the transmitted optical signal into an electrical signal and transmits it to the next level of equipment.
The main function of a digital optical transceiver is to digitize the image, voice, and data signals to be transmitted, and then reuse these digital signals to convert them into optical signals; At the receiving end, the optical signal is restored to an electrical signal, which is the original image, voice, and data signal.
Difference
The similarity between fiber optic transceivers and optical transceivers is that they both require photoelectric conversion. The difference is that fiber optic transceivers only perform photoelectric conversion without changing the encoding or processing data. They are mainly used in networking such as banks and education; In addition to processing photoelectric conversion work, optical transceiver also needs to process data signals, mainly used in fields such as security monitoring, remote education, video conferencing, etc. that require high timeliness for video transmission.
