DWDM gratings are used to extract or insert paths in DWDM systems to increase or decrease filtering. The requirement of channel isolation is very high in DWDM system, in order to avoid cross-interference between channels. Our company can provide gratings with path spacing of 100 GHz or 50 GHz, featuring flat top, high isolation, low insertion loss and low polarization-related loss. It can be packaged separately or used as all optical division/insertion multiplexer by customizing grating strings.
