PLC MODULE HAVING SINGLE INPUT/OUTPUT TERMINAL

摘要

PURPOSE: A PLC(Planar Lightwave Circuit) module having a single input/output terminal is provided to miniaturize a total size by installing a fiber array block coupled to a waveguide on one side of the PLC module. CONSTITUTION: A PLC module having a single input/output terminal includes a fiber array block(100), an input waveguide(102), an output waveguide(114), and a reflection side(106). The fiber array block(100) is coupled to one side of the PLC module. The input waveguide(102) and the output waveguide(114) are coupled to the fiber array block(100). The reflection side(106) is coupled to the other side of the PLC module in order to induce a traveling path of the light through the input waveguide(102) to the output waveguide(114).
