“…Over the past two decades, 2-D TW OCDMA techniques in optical fiber networks have received considerable research interest because of their ability to increase the system user capacity, provide multiple-user access, employ asynchronous operation and support high speed applications [1][2]. In 2-D TW OCDMA schemes, each user is assigned a signature code which is spread in time and wavelength in order to minimize the multiple access interference and to maximize the number of subscribers.…”

The behavior of four-wave mixing (FWM) in 2-D time-spreading wavelength-hopping (TW) optical code-division multiple-access (OCDMA) systems with coherent light sources is introduced. The analysis is performed in terms of several key system parameters, in particular, transmitted power per chip, wavelength spacing, number of active users, code weight,fiber type, and transmission length. To accomplish such study, the number of generated FWM components should be calculated first. Thus, for the first time, a general form for the FWM power generated in 2-D TW OCDMA systems is presented and explicit formulas for the number of FWM products that fall on each signal chip for symmetric codes are given.
