Abstract:
1. An optical node, comprising: a number A of optical demultiplexers, each demultiplexer adapted to provide at its N output ports respective incoming optical signals received from respective N optical cores of an incoming optical multi-core fiber or received from N multimode signals of a spatially multiplexed multi-mode fiber; maximally M optical switches having maximally A*N input ports and maximally M*N output ports, wherein M is a maximum value of the numbers A and B; A*N optical splitters each adapted to receive one of the incoming signals and to split the received one incoming signal onto one input port of each of the optical switches; and B*N wavelength selective switches each wavelength selective switch adapted to receive maximally M incoming optical signals from output ports of the optical switches and to combine the received incoming optical signals onto a respective same input port of one of the multiplexers, wherein the optical node is configurable
