High capacity communications satellite
First Claim
1. A method for optically switching a signal in a two-way communication system using only one satellite, comprising the steps of:
- receiving a first set of N beams;
forming a first set of N optical channels from respective ones of said N beams;
spreading each of said first set of N optical channels in one dimension to irradiate a first N×
M array;
switching a signal existing at one position of the first N×
M array to any position of a second N×
M array;
unspreading the signals from said second N×
M array to form a second set of N optical channels;
forming a second set of N beams from said second set of N optical channels; and
transmitting said second set of N beams, said second set of N beams servicing M customers simultaneously.

Abstract
A method for optically switching a signal in a two-way communication system using only one satellite includes the steps of receiving a first set of N beams, forming a first set of N optical channels from respective ones of the N beams, spreading each of the N optical channels in one dimension to irradiate a first N×M array, switching a signal existing at one position of the first N×M array to any position of a second N×M array, unspreading the signals from the second N×M array to form a second set of N optical channels, forming a second set of N beams from the second set of N optical channels; and thereafter transmitting the second set of N beams which service M customers simultaneously.
