H04B10/2933 - CPC Classification

Classification description:

Transmission systems employing electromagnetic waves other than radio-waves, e.g. infrared, visible or ultraviolet light, or employing corpuscular radiation, e.g. quantum communication; Repeaters in which processing or amplification is carried out without conversion of the main signal from optical form; Signal power control considering the whole optical path

Sub-classes:

H04B10/2935 » {with a cascade of amplifiers} 64
