Abstract

In cascaded optical networks, the BER performance of optical CDMA (OCDMA) signals has been evaluated. In order to simulate the optical link, the optical source, receiver, and fiber channel are modeled as lowpass filters by using Butterworth/Chebyshev approximations. Bipolar codes are used for spreading, and at the chip rate of 8 Gc/s, multi‐user interference (MUI) and distortion introduced by the optical link are found to be insignificant. © 2004 Wiley Periodicals, Inc.
