Based on the nonlinear detection principle of photodiodes and the coherence time of optical sources a general receiver model is deduced. From this model nine elementary structures can be found, enabling the theoretical analysis of all known schemes. Moreover, we derive general rules for the utilization of suitable code families for possible structures.encode division multiple accessencodingoptical fibre communicationoptical fibre lanoptical receiverfiber-optic cdmaoptical code division multiple accessnonlinear detection principlephotodiodecoherence timeoptical sourcegeneral receiver modelcode familyoptical cdma lan621conference paper
