Incoherent systems need to physically compensate DCK to solve the dispersion problem. The following descriptions about the position of DCM in the network and optical power requirements, which…
The correct answer is A. For the OAU amplifier scenario, the DCM can be placed between the TDC-RDC ports of the OA board C. DCM is a purely passive device and has no requirement for single-wavelength optical power D. For the OBU amplifier scenario, the DCM can be placed before the IN port of the OBU board. See the full explanation below for the reasoning.
