An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent. Fundamentals of 5G Waveform, Numerology, and Frame Structure (Explanation of the fundamental concepts of 5G NR design, waveform, numerologies, and frame structures. 3.
