Slot device for exchanging information between information devices based on light communication

PURPOSE: A fabric slot apparatus for exchanging information is provided to exchange information between information apparatuses regardless of LoS(Line of Sight) by using optical fiber as light transmission routes. CONSTITUTION: Each slot(110-1~110-3) includes a light collecting unit(130-1~130-3) and a light spreading unit(140-1~140-3). The light collecting unit collects the light in order to transmit light emitted from an information apparatus(120-1~120-3) to other slot. The light diffusion unit diffuses light transmitted to other slots. The light diffusion unit of the one slot contacts to other slot of the light collecting unit through an optical fiber(106). The light collecting unit of the one slot contacts to the light diffusion unit of other slot through the optical fiber.
