    摘要: An optical data is transmitted from station to station through an optical T-coupler (2) attached to each station. The optical T-coupler (2) splits the data signals into two paths with identical data being transmitted to the attached station and also the succeeding station. An optical to electric conversion takes place as the data enters a station interface unit (3). Electronic digital switching within each station interface unit (3) selects a "normal" mode of receiving data from the preceding station when data is valid, or a "bypass" mode of receiving data from the station which precedes the preceding station when the data is invalid. Switching from normal to bypass mode is performed by electronic switching and requires no optical switches.

    摘要: Ce coupleur est du genre dans lequel des moyens de collimation (10) sont interposés entre la source de lumière (20) et la ligne de transmission (14). Les moyens (10) comportent un noyau transparent sphérique (26) présentant un certain indice de réfraction, entouré d'une enveloppe transparente (24), également sphérique, et présentant un indice de réfraction inférieur à celui du noyau (26). Le faisceau lumineux conique issu de la source (20), traverse successivement l'enveloppe (24), le noyau (26), puis à nouveau l'enveloppe (24), ce qui a pour effet de le concentrer et lui donner une section comparable à celle de la fibre optique (30) de la ligne (14). La source lumineuse (20) est montée au fond d'un logement cylindrique dont les bords sont collés sur l'enveloppe (24) après que celle-ci a été orientée de façon que la fibre (30) reçoive le maximum de lumière.

    摘要: A fiber optic scanner system (10) for reading coded patterns is provided having a single optical fiber extending from the reading end of the scanner tip to a remote terminal (36). The remote terminal includes an optical signal generator (44) for generating and driving light pulses along the single optical fiber to the reading end of the scanner member so as to illuminate a bar code and obtain reflected pulses therefrom which are carried to the remote terminal receiver (46) and decoded.
