An apparatus for the selective routing of information signals includes a plurality of transmitting units. Each transmitting unit has a transmitter for transmitting information by converting the same into a light signal. A plurality of fiber optic lines are provided for carrying the light signal from the transmitting units. Each fiber optic line corresponds to one of the transmitting units. At least one receiving unit is provided for selectively receiving the information carried by the fiber optic lines. The receiving unit includes a liquid crystal panel having a plurality of light passing areas. The optical transmission properties of the light passing areas are controlled individually, for selectively receiving the light from the fiber optic lines, for effecting connections between the transmission units and the receiving unit by the fiber optic lines in any arbitrary combination. Each light passing area corresponds to one of the fiber optic lines. A receiver which is part of the receiving unit generates an electrical signal converted from the light which passes through the liquid crystal panel.
