For the first time, simulations have been performed to evaluate and compare the link power budget and power dissipation of 100 Gb/s carrierless amplitude and phase modulation-16/64 (CAP-16/64) and 16/64-quadrature amplitude modulation-orthogonal frequency division multiplexing (16/64-QAM-OFDM) systems over feedforward error correction (FEC) enhanced single mode fiber (SMF) links using an 18.6 GHz bandwidth directly modulated laser, for both single channel and two coarse wavelength division multiplexing (CWDM) channel cases. It is shown that single channel CAP-16 and 16-QAM-OFDM links can successfully support transmission over 5 km SMF, with a power dissipation of 2 times that of a 4 25 Gb/s NRZ system. Even when the loss of the optical multiplexing/demultiplexing operations is considered, the use of two CWDM channels supports transmission over 5 km SMF with CAP-16 and 16-QAM-OFDM. The CWDMsystems do not increase transceiver power dissipation greatly.
