Embodiment Construction
[0064] figure 1 It is a flow chart of the erasing and inserting method of differential eight phase shift keying / amplitude shift keying quadrature optical marks based on the electroabsorption modulator of the present invention. Combine now figure 1 , the method of erasing and inserting the differential eight-phase shift keying / amplitude shift keying orthogonal optical mark based on the electroabsorption modulator of the present invention is described, specifically as follows:
[0065] Step 11: On the edge router (Edge Router), load the payload and tag information to the phase and amplitude of the optical carrier, respectively, to form a differential eight-phase shift keying signal / amplitude shift keying (D8PSK / ASK: Differential 8-Level Phase -Shift Keying / Amplitude-Shift Keying) quadrature modulation signal.
[0066] In this step, the method of loading the payload and the marker information to the phase and amplitude of the optical carrier respectively includes:
[0067] In ...
