Draw the diagram for a non-reconfigurable optic switching system with three optical fibers as input - ports and three optical fibers as output - ports. Every optical fiber transmits three lightpaths or lambda channels, which must be transferred from the input optical fiber to the output optical fiber according to the switching matrices shown in Figure 1.

Please explain step-by-step.
