Abstract
The peak-to-average power ratio (PAPR) of a next generation data center optoelectronic communication system is analyzed. A new challenge of ultrabroadband signals transmission over coupled printed transmission lines (PTLs) is introduced for the case of separated design of the optical module and on-board electronics. PAPR enhancement models are developed for transmission of ultrabroadband signals over coupled PTLs, due to enhanced coupling impairments. High instantaneous peak power values may lead to compression and nonlinear distortions due to the limited dynamic range of the communication system components. The analysis, which is verified by Monte Carlo simulations, reveals that the instantaneous PAPR increases significantly.
