Abstract:
An optical signal transmission device for transmitting optical signals, comprising:light-guide layers having optically reflecting outer surfaces and formed of a material being at least low-loss for optical waveguides used for optical signal transmission; at least one electric printed circuit board for transmitting electric signals disposed on one of said light-guide layers, said light-guide layers and said at least one electric printed circuit board form a signal transmission plate configuration; a number of optical signal output elements disposed in said signal transmission plate configuration and having light output regions each aligned with a respective one of said light-guide layers for outputting the optical signals; and a number of optical signal reception elements disposed in said signal transmission plate configuration and having light reception regions each aligned with a respective one of said light-guide layers for receiving the optical signals, said optical signal output elements and said optical signal reception elements can be operated in a wavelength-specific fashion in each case on their own.
