The difference between a fiber optic transceiver and an optical transceiver [Application]

Fiber optic transceivers and optical end of the same: have to photoelectric conversion the difference: The role of fiber optic transceivers photoelectric conversion, do not change the code, not for other data processing, the transceiver is for Ethernet, run 802.3 protocol, only for point-to-point connection. You can achieve 0-120Km between the two switches or the connection between the computer, but the practical application has more expansion. 1, to achieve the interconnection between switches. 2, to achieve the exchange between the switch and the computer. 3, to achieve the interconnection between computers. 4, transmission relay: When the actual transmission distance exceeds the nominal transmission distance of the transceiver, especially when the actual transmission distance of more than 120Km, in the case of field conditions permit, the use of two transceivers back to back relay or use light - Optical converter for relaying, is a very cost-effective solution. 5, single multi-mode conversion: When the network needs a single multi-mode fiber connection, you can use a multi-mode transceiver and a single-mode transceiver back-to-back connection to solve the single multi-mode fiber conversion problem. 6, wavelength division multiplexing transmission: When the long-distance cable resources, in order to improve the use of cable, reduce the cost, the transceiver and WDM can be used in conjunction with the two information on the same fiber transmission. Optical, in addition to the work of photoelectric conversion, but also on the data signal reuse and demultiplexing. Usually the optical machine is out of the many E1 lines. SDH, PDH optical transceiver is mainly used for telecom operators, to provide many pairs of point to the point of the data circuit; video Guangduan Ji mainly for security monitoring, distance education, video conferencing and other video transmission requirements of relatively high real-time areas, and can Transmission control, switch, voice, Ethernet and other signals to meet the needs of multi-service applications, so we sometimes call it Integrated Optical
