Ukubuka konke

Uma kuqhathaniswa nezinhlelo ze-RF zendabuko, ukuxhumana nge-laser kunikeza i-bandwidth ephezulu kakhulu, ukusetshenziswa kwamandla okuphansi, kanye nokulwa nokuphazamiseka okuphezulu kanye nokuphepha. Kufanelana kahle nezinkanyezi ezinkulu, ukubuka uMhlaba, ukuhlola isikhala esijulile, kanye nokuxhumana okuphephile/okulinganiselwe.

Iphothifoliyo ihlanganisa ukuhlanganiswa kwe-optical okunembe kakhulu, ama-terminal e-laser aphakathi kwe-satellite kanye ne-satellite-to-ground, kanye nohlelo lokuhlola oluphelele olufana ne-far-field test—okwakha ikhambi eliphelele elivela ekugcineni kuya ekugcineni.
