We propose and model an optical communication scheme for short distance datacom links based on the distribution of information across a wide comb spectrum. This modulation format, orthogonal delay division multiplexing, allows multiplexing data streams from multiple modulators, as well deserialization equalization in domain. A concrete system, that transport 400 Gb/s single CWDM channel with 80 GHz cutoff lithium niobate insulator modulator, is modeled under consideration all noise sources present system its sensitivity to group velocity dispersion analyzed. Data deserialized equalized at receiver 5-tap equalizer. architecture may provide path forward implement high-baud-rate signaling short-reach without requiring high-speed ADCs electronic deserializers receiver, thus maintaining in-package power consumption manageable levels.
