摘　　要：A new family of two-dimensional optical orthogonal code(2-DOOC), namely, modified quadratic congruence code(MQCC )/optical orthogonal code(OOC) is proposed who employs MQCC and OOC as wavelength hopping and time-spreading patterns, respectively. Through analyzing the performance of MQCC/OOC, we can see that the correlation properties of the MQCC/OOC are still ideal. Simultaneously, our analysis shows that the proposed new code families can get more cardinalities than other codes and can improve the bit error rate(BER) of optical code division multiple access(OCDMA) effectively.A new family of two-dimensional optical orthogonal code（2-DOOC）, namely, modified quadratic congruence code（MQCC ）/optical orthogonal code（OOC） is proposed who employs MQCC and OOC as wavelength hopping and time-spreading patterns, respectively.
