After summarizing the application of linear, quadratic and hyperbolic operators in CDMA system, a generalized algebraic congruent code is given out by its construction formula in three different categories, which are frequency-hop (FH), time-spread (TS) and FH-TS codes. A novel two-dimensional optical CDMA system is given out, in which different categories of codes are used to provide different types of service. Such a OCDMA system is very fit for the case that a small part of services are with high bit rate or high quality of service, while great amount of services are common one. In order to prove the possibility of such a hybrid system, the cross-correlation constants between those three codes are given firstly, the probabilities to attend those cross-correlation values are calculated secondly, system's BER performances under several different types of interferences are provided at last. Numerical analysis and discussion is also given.
