PLC splitter is based on planar lightwave circuit technology and precision aligning process. It can divide a single/dual optical input(s) into multiple optical outputs uniformly and is denoted 1xN or 2xN. PLC splitter is applied in FTTX deployments, PON networks, CATV links and optical signal distribution.
