PLC design

A PLC consists of a chip and two fiber arrays. The chip is the primary component in any PLC. The chip contains the waveguide structures that are needed to combine and/or split the waveguides. The fiber array affixed to the chip front connects the chip inputs and outputs with the fibers. This flexible technology means that almost any input/output ratio is feasible (see product portfolio).
