Abstract :
We propose and simulate a code-division-multiplexing (CDM) over-fiber passive optical network (COF-PON) system using novel logical operation coding to eliminate multiple access interference (MAI). In this COF-PON system, CDM is accomplished in the frequency domain. At the transmitter, data from each user is encoded with a group of selected subcarriers, and then fed through the fiber. Non-linear effect of the transmission fiber is also considered. This coding method is simple and cost-effective. With the simulation, we tested and compared the Q factor of 1Gb/s and 0.5Gb/s downstream signals, and proved the proposed coding scheme to be feasible.
