A new two-dimensional optical orthogonal code named SQPC/OCS was constructed with synchronous quadratic prime code (SQPC) as time spreading sequence and one-coincidence sequence (OCS) as wavelength hopping sequence. The performances of bit error ratio (BER) and word capacity were compared by analysis and simulation. Theoretical analysis show that SQPC/OCS has the same BER as 2D-QPC (Quadratic prime code) when given the same code length and same number of wavelength, but SQPC/OCS can reduce its BER by increasing the number of wavelength which is not limited to a prime number. Compared with extend prime code (EPC) EPC/OCS, SQPC/OCS gets lower BER. Moreover, the code capacity of SQPC/OCS was much more than that of 2D-QPC and EPC/OCS. The simulation shows that the bit error rate (BER) of SQPC/OCS is nearly two orders of magnitude lower and four orders of magnitude lower than that of 2D-QPC (p=7 and q=13) and EPC/OCS (p=11 and q=15) while the number of synchronous users equals 20, respectively.
