Abstract

A free-space redundant optical communications infrastructure and appurtenances for use therewith are presented wherein 'partial aperture' functions such as beam splitting into a plurality of sub-beams and dividing an aperture into substantially segmented areas for respectively transferring such sub-beam are disclosed. These partial aperture functions are taught for transceivers, transmitter apparatus, receiver apparatus, and for hybrid combinations thereof. Furthermore, optical communications grating components presented for use therewith and for use in fiber transmitted optic beams are discussed.
