A “pairwise transmission” technique is discussed for dispersion-limited multilane IM-DD systems. C-band optical-amplification-free 112Gb/s/lane over up-to-40km SMF (~640ps/nm dispersion) with low-complexity digital equalizers is demonstrated, showcasing 4-fold reach enhancement beyond conventional IM-DD.
