112 Gb/s/λ CAP Signals Transmission over 480 km in IM-DD System

We demonstrate a 112 Gbit/s/λ CAP over 480 km of SSMF with low-cost direct detection. A joint processing algorithm is employed to improve system performance. To the best of our knowledge, this is the first time that single-wavelength 100G signal transmission is experimentally achieved over 480 km of SSMF with CAP-16 and direct detection.
