ABSTRACT:
A TT coupler for use in fiber optics data transmission systems wherein the incoming light to the coupler passes to both the receiver of the subscriber station and through the coupler lead toward the next subscriber station in succession in a ratio controlled by the design and geometry of the coupler. Signals not addressed to that station are identified as such by the receiver for that station and are regenerated and/or amplified and then passed to the transmitter for that station to be returned into the appropriate portion of the aforesaid coupler. The failure of one or even several receiver-transmitter facilities in succession will not degrade the system to the level of becoming inoperative due to the coupler design and its interaction with the receiver-transmitter facility at each subscriber station.
Means are provided for monitoring signal strength at each station and for providing necessary amplification in cases where it is so required.
