According to the Ministry of Public Security's Order No. 82, “Technical Measures for Internet Security Protection,†all Internet units or service providers are required to deploy Internet security and information security. The network monitoring system is called the network information monitoring system. By analyzing the contents of all the networks, it can prevent the leakage of sensitive information generated by internal computers through the Internet in time, quickly locate the source of the tracing, prevent the occurrence of violations, and access the entire network and computer users. Behaviors and network traffic are monitored to help the network operate efficiently, stably, and securely. Computer users are prevented from accessing illegal sites, transmitting and distributing illegal information, and preventing violations of network resources and leaking sensitive information. It is a necessary means for computer users to conduct network behavior and content detection.
solution
The optical path data link acquisition system consists of a primary link optical splitter, a replication link OEO optical amplifier, and a replication link optical splitter. The schematic diagram is as follows:
Optical Path Technology copies the optical signal on the original link by connecting the optical splitting port in the original link, and then adding the optical amplifier to the optical signal for reinforcement.
The main link optical splitter adopts 1:2 splitting, and the split ratio is 70:30;
The replica link optical amplifier adopts the OEO mode to reproduce and amplify the signal;
The replication link optical splitter adopts 1:4 splitting, and each branch is split by average;
