Spatial domain based multi dimensional coded modulation for multi Tb per second serial optical transport networks

摘要

An optical transport network based on multimode/multicore fibers includes a mode-multiplexer to multiplex independent data streams from one or more transmitters; a multimode erbium-doped fiber amplifier (MM EDFA) to compensate for MMF loss; a multimode optical add-drop multiplexer (MM OADM) to add and/or drop multimode channels in multimode networks; a multimode optical cross-connect; and a mode-demultiplexer to separate various mode streams to one or more receivers.

1. An optical transport network, comprising:
a. a mode multiplexer to combine inputs from one or more transmitters; b. a multimode erbium-doped fiber amplifier (MMEDFA) to compensate for multimode fiber loss; c. a multimode optical add-drop multiplexer (MMOADM) to add and/or drop multimode signals; d. a multimode optical cross-connect; and e. a mode demultiplexer to separate the mode-multiplexed streams and provide data to one or more receivers f. code to determine Laguerre-Gauss (LG) and vortex beams with a field distribution of an LG beam traveling along the z-axis in cylindrical coordinates (r,φ,z) (where r denotes radial distance from propagation axis, φ denotes azimuthal angle and z denotes propagation distance).
