- DVOP-IN-H-EG4 Gigabit 4-channel physical isolation network optical terminal
- DVOP-IN-H-EG4 series is a network fully isolated optical terminal with complete core intellectual property rights of Guangxiang. It uses dedicated ASIC and adopts fully isolated channel isolation technology to achieve complete isolation between different multi-network signals. Channel isolation technology adopts TDM (Time division multiplexing) technology for different types of network information. Different kinds of network signals are transmitted by different time-slot channels, and each network signal has a unique and independent TD time-slot for transmission. This method is used to achieve isolation on the hardware channel, and this isolation method makes it impossible to invade another network from one network, so as to realize the bottom isolation between different network signals. At the same time, in the way of implementation, this fully isolated design adopts the way of large-scale logic FPGA devices, and there is no software in the device, and it also fundamentally eliminates brute force cracking, or dismantling cracking and other means, which has strong security. Products support centralized management rack card application, support centralized network management function, seamless access to our security monitoring centralized management platform e-MS, support optical path alarm, support network alarm, with front-end power off alarm function, support remote machine and local machine integrated transmission system management function. The open interface design allows integration into higher level network management systems.
