%X A new two-dimensional optical orthogonal codes named EPC/OCS is firstly constructed,using EPC(extend prime code) for time spreading and OCS(one-coincidence sequence) for wavelength hopping.Cross-correlation performance of EPC/OCS is analyzed.Compared with MPHC,the number of wavelengths for EPC/OCS is not limited to prime number.EPC/OCS can be constructed flexibly,and also can use available wavelengths adequately.When the number of wavelengths is larger than prime number,EPC/OCS not only has larger code cardinality,but also has better cross-correlation performance.Theoretical analysis shows that EPC/OCS can reduce the bit error rate(BER) of MW OCDMA networks.
