Abstract
It is an object of the invention to make an optical receiver for an OCDM network addressable both individually and as part of a group of optical receivers. The optical receiver according to the invention is particularly characterized in that it comprises a series combination of two optical filters having different periods. One of the periods serves to receive broadcast signals. By selecting this period at the transmitting end, a group of optical receivers each incorporating a filter with this period can be selected and a data signal can be transmitted to this group simultaneously. The other period serves to control the reception of signals individual to each receiver, with the sum and/or the difference of the two periods being used for receiving the individual signals.
