Based on the photonic vector signal generation of self-starting OEO, using MZM to generate OEO signals, using a programmable optical processor (POP) to separate the upper and lower straps of oEO, using DPMZM to obtain carrier suppression unilateral bands (CS-SSB) and OEO upper band, PD detects the external frequency of the two optical sidebands, resulting in a octave vector signal.
