Transceiver: Transceiver is a device of signal conversion, usually refers to optical transceiver. The emergence of optical transceiver, the twisted pair signal and optical signal are converted to each other to ensure the smooth transmission of data packets between the two networks. At the same time, it expands the transmission distance limit of the network from 100 meters of copper wire to 100 kilometers (single mode optical fiber).
Interface type
According to network management, it can be divided into network management type optical transceiver and non-network management type optical transceiver.
With the development of network toward operational and manageable direction, most operators hope that all devices in their network can be managed remotely. Fiber optic transceiver products, like switches and routers, are gradually developing in this direction. At present, most vendors'network management systems are developed based on SNMP network protocols, which support various management modes such as Web, Telnet, CLI and so on. The management content includes configuring the working mode of the optical transceiver, monitoring the module type, working state, cabinet temperature, power supply state, output voltage and output optical power of the optical transceiver, etc. With the increasing demand of operators for equipment network management, it is believed that the network management of optical transceiver will become more practical and intelligent.
Fiber optic transceiver breaks the 100-meter limitation of Ethernet cable in data transmission. Depending on high-performance switching chip and large-capacity buffer, it realizes the real non-blocking transmission and switching performance, and also provides the functions of balancing traffic, isolating conflicts and detecting errors, so as to ensure high security and stability in data transmission. Sex. Therefore, in a long period of time, optical transceiver products will still be an indispensable part of the actual network construction. In the future, optical transceiver will continue to develop in the direction of high intelligence, high stability, network management and low cost.
