PURPOSE: An optic cross-state connection device for a wavelength division multiplexing transmission selectively switches the data loaded on a plurality of wavelength channels transmitted via many optic fibers of a network using a wavelength division multiplexing method. CONSTITUTION: An optic cross-state connection device for a wavelength division multiplexing transmission includes an optical input/output part for receiving an optical signal from outside or transmitting the transmitted optical signal to the outside. A routing part disperses the optical signal generated from the optical input/output part or an optical switching part, transmits the dispersed optical signals to the optical switching part or the optical input/output part, and simplifies a structure without reducing a transmission path by using a first reflection mirror(511). The optical switching part performs a switching process about the routing part in order to achieve a cross-output of the optical signal transmitted from the routing part, and simplifies a structure without reducing a transmission path by using a second reflection mirror(517). |
