Resumo: | The purpose of this work is to describe and demonstrate a new concept of a hybrid communication system, which consists of applying electrical CDMA on a system using optical WDM. Each user has a unique orthogonal CDMA code and modulates an electrical carrier (e.g. QPSK) prior to the data directly modulating an optical carrier. Thus, it is possible to add several data channels in an optical fiber, over the same or different optical carriers, and recover the information associated to each of the channels. With this approach we can avoid the use of optical filters at reception, making the system more flexible and robust. |
