Time-Delay Interferometry (TDI) is the main method for reducing laser phase noise in space-based gravitational wave detection. In addition to inter-spacecraft signal delays, onboard optical delays within each spacecraft, including the local, adjacent, and distant paths, can affect practical detection. As a result, laser phase noise is not fully canceled and residual noise remains. This work extends the previous analytical approaches by deriving the residual laser phase noise for 45 geometric TDI
