Abstract
The present invention relates to an optimized guided wave microwave or lightwave communication system or network wherein a plurality of directional couplers (14, 17) (a) are disposed along a bus-like wave guiding means (13, 16), and (b) include separate coupling coefficients which are optimized. More particularly, the present invention relates to a guided wave communication system or network including, for example, a head-end unit (15) which is coupled to one end of a bus-like wave guiding means. Separate directional couplers are disposed along the wave guiding means to couple lightwave or microwave signals either (a) into the bus-like wave guiding means (13) from separate transmitters (11), or (b) from a bus-like wave guiding means (16) to separate receivers (12). The directional couplers disposed along a guiding means each include a separate coupling coefficient which is optimized to only couple enough of the lightwave or microwave energy onto or from the associated guiding means so that either (a) the head-end unit receives a minimal signal power level from each transmitter or (b) the receivers receive a minimal signal power level from the head-end unit, respectively, to provide…
