“…H. S. Z. Dam et al [22] developed a novel encoding and decoding technique that took advantage of two orthogonal polarization states (vertical and horizontal) of an optical code to increase the number of simultaneous users in FTTH networks. They applied SAC-OCDMA codes in both Optical Fiber Systems (OFS) and Free Space Optics (FSO).…”

We propose the 1-D Two-Distinct codes with two-code keying (TCK) using two mutually orthogonal states of polarizations (SOPs) in spectral components as a new code family for spectral amplitude coding (SAC) in optical code division multiple access (OCDMA) networks. Our proposed structure of the proposed codes operates the 1-D Two-Distinct codes with TCK using two mutually orthogonal SOPs in spectral components to achieve the simple architecture. The modified cross-correlation within the 1-D Two-Distinct codes with TCK facilitates the transition from one code keying (OCK) to the generation of TCK. We design the 1-D Two-Distinct codes with TCK to eliminate the multiple user interferences (MUIs) caused by other simultaneous users through modified cross-correlation, thereby improving code operation. Although the recovered bits are affected by the phase-induced intensity noise (PIIN), our proposed system can suppress the PIIN. Numerical results show that our proposed system supports up to a number of simultaneous users of 45 and provides higher data transmission rates of 2.5 Gbps compared to the other systems using 1-D SP codes with TCK, 1-D BIBD codes, and 1-D BDS codes with TCK.INDEX TERMS cross-correlation, multiuser interference, one code keying, optical code division multiple access, and two code keying.
