This is a computer science - the physical layer report. Please help me with this one

Explain in detail 1. Wavelength division multiplexing and communications using optical fibers 2. Thw complete design of a wavelength division multiplexed system, as shown. 3. The whole process to transfer the data signal over a single mode fiber network system based on wavelength division multiplexing.
