Abstract

A signal transmission plate configuration is described for transmitting optical signals between a number of optical signal output elements and a number of optical signal reception elements. The signal transmission plate configuration contains at least one electric printed circuit board, at least one light-guide layer whose outer surfaces are optically reflecting, and optical signal output elements and optical signal reception elements inserted into the plate configuration with their light output regions and light reception regions, respectively, aligned for outputting or receiving optical signals. The optical signal output elements and the optical signal reception elements can be operated in a wavelength-specific fashion in each case either on their own or in conjunction with transmitting or receiving units assigned to them.

Dependent claims

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.
