For the purpose of realizing the optical channel monitoring in WDM systems with 50 GHz channel intervals
we present a design of diffractive grating-based Optical Channel Monitor(OCM) and introduce its working principle.Then we calculate and analyze its insertion loss
working range
response time
wavelength and channel resolutions and conduct experimental tests on the sample.The results show that this OCM module can accurately monitor the channel wavelength and power performance of the WDM systems at 50 GHz intervals and with hybrid transmission rates of 10 Gbit/s/40 Gbit/s.
