Embodiment 1
[0035] Such as figure 2 As shown, the optical multicast network of this embodiment is composed of one source node and 18 destination nodes, wherein nodes 1-16 form a multicast group. The source node is composed of a tag generation module and a data generation module. In the tag generation module, firstly, a 2ps pulsed fiber laser generates a short pulse sequence with a repetition rate of 10GHz, and the pattern generator generates an electrical pulse sequence of 311.25Mb / s, which is phase-shifted by a microwave phase shifter and then output to control the intensity modulator 1. After the 10GHz short pulse sequence passes through the intensity modulator 1, the repetition frequency is reduced to 311.25MHz, which is the data packet rate. The pulse sequence is encoded after passing through EDFA (Erbium-doped Optical Fiber Amplifier), circulator and optical label encoder, and the generated two-dimensional coded optical label is used to mark the multicast group.
