OCDMA is one of the promising optical access technologies because of its notable characteristics, including asynchronous access and enhanced security. In this paper, the author introduced a new universal equation for the DW coding family The universal DW code equation allows for the construction of a new code structure, with either even (EW) or odd (OW) code weights. Contrast this with the previous formula, which contains separate equations for even and odd weights. Double Weight code has a fixed weight value of 2. EW and OW codes are variants of the Double Weight (DW) code family with weights above two. OW is unevenly weighted, while EW is evenly weighted. EW and OW were implemented in transmission connections to reduce noise and Multiple Access Interference (MAI). The revised equations for EW and OW can be used to calculate performance in order to measure the effectiveness of the code. Combining the current MDW and EDW codes yields the new equation. OW performs much better than the Hadamard, MFH, EW, and DW codes. OW can accommodate more than eighty concurrent users. © 2024 Author(s).
