Abstract
Due to modal dispersion in OM4 fiber, multi-mode VCSELs have a limited high-speed NRZ and PAM4 transmitting distance of below 100 meters. The single-mode VCSELs with integrated mode-selective filter has been developed and demonstrated 96 Gb/s PAM4 transmitting distance to 1km with 1.78 dB TDECQ and 112Gb/s over 100 m OM4 fibers.
