In this paper, the impact of optical beat noise on the performance of optical fast frequency hopping code division multiple access (FFH OCDMA) networks is analyzed. BCH/FFH OCDMA to reduce the impact of optical beat noise is proposed. It is shown that, BCH/FFH OCDMA has much better performance under the same bit rate, same chip time and same number of available wavelengths. Another advantage for BCH/FFH OCDMA is that the code length of one-coincidence sequence will be shorter, which can greatly reduce the difficulty of fabrication for fiber gratings.
