Most studies regarding OCDMA systems have assumed perfect synchronization.
The OC technique utilizes the spreading codes that have been used in OCDMA systems, such as optical orthogonal code (OOC) and PC .
A system that uses an incoherent OCDMA is based on the binary 1 and 0, where 1 represents the presence of light and hence the encoding process executes and generates a waveform s(n).
OCDMA systems can be classified into two types, according to the choice of optical sources: coherent and in-coherent OCDMA.
(iii) cost of TDM and OCDMA based OLT and ONUs is taken to be the same,

In this paper, we propose a new family of new codes for OCDMA systems named 1D active weight two-code keying (TCK) codes.
We propose one-dimensional (1D) active weight TCK codes for use in spectral amplitude coding (SAC) OCDMA networks.
Multiple access interference is the primary source of performance deterioration in large cardinality OCDMA systems.
Therefore, DDW code suing SPD technique is an efficient choice for the implementation of next generation OCDMA networks.
For an OCDMA system with N transmitter and receiver pairs (users), the received signal [y.sub.out] (t) is the sum of N user's transmitted signals, which can be given  by
The results obtained in the present study demonstrate that the OCDMA system performance with inline optical amplifiers can be improved remarkably in presence of GVD and SPM using Hyperbolic-Secant shaped user address by operating the system at optimum input signal power.
