The performance assessment of a novel multilevel modulation format based on partial‐response signalling called absolute added correlative coding (AACC) by numerical simulations is delineated, targeting short‐range and interconnect high‐speed optical networks. The spectral efficiency, chromatic dispersion tolerance and receiver sensitivity of 4‐instensity level AACC are discussed and compared against other well‐known existing modulation formats, namely, non‐return‐to‐zero on–off keying and 4‐ary pulse‐amplitude modulation (4‐PAM). The robustness of the higher order of AACC over 8‐PAM and 16‐PAM is also discussed.
