Abstract: In order to maintain the security of the optical network while meeting the current requirements of large capacity, high bandwidth, and low power consumption for data communications, an optical packet filtering system based on all-optical pattern matching is proposed. This system can identify and filter out the optical packets containing the specified address sequence under all-optical conditions, thereby realizing the protection of the optical network. First, the all-optical pattern matching module matches the optical packet address sequence with the target sequence, and then generates a control signal according to the matching results to control the passing or filtering of optical packets. The system was verified by simulation using VPItransmissionMaker software, and the results show that the system can achieve the filtering function of optical packets with specified address sequence at a transmission rate of 100Gbit/s.

Key words: optical network security, all-optical pattern matching, optical packet filtering
