Multi-band filter in PON Application

From the application level, compared with the 5G solution, the Passive Optical Network (PON) solution has more feasible, lower cost, better performance, and stronger competitive advantages.
Compared with the optical Ethernet solution, industrial PON has fewer layers, lower cost, more reliable features, easier to be expanded, and satisfy telecom operation experience.
Our multi-band filters are demonstrated with many advantages in GPON, XG-PON, XGS-PON module applications. New generation of muti-band filter designs are applying in PON module recently. They are required in narrower pass band and reflect band width, steeper in transit band, and custom center wavelengths design comparing to traditional CWDM multi band filters.
