摘要
The invention relates to a method for optical coding of a broadband signal, to an optical coder. In order to enable an efficient increase in the number of codes for an OCDMA system, the method comprises coding the signal by frequency-hopping and coding the frequency-hopping coded signal temporally or coding the signal temporally and coding the temporally coded signal by frequency-hopping. The proposed optical coder 10 comprises corresponding means 20, 30. The invention relates equally to a network architecture for optical coding of broadband signals originating from a plurality of users 50 or for optical decoding of an encoded broadband signal destined for a plurality of users 50 with distributed means for frequency-hopping and temporal coding.
