Distance-adaptive super-wavelength routing in elastic optical path network (SLICE) with optical OFDM

Abstract

We propose a spectrally-efficient super-wavelength-path routing in SLICE by selecting a set of subcarrier numbers and modulation levels according to path distances. We demonstrate 420 Gb/s path routing using short-reach 14-subcarrier 8-APSK and long-reach 21-subcarrier QPSK.
