Abstract
OFDMA-PON is an attractive candidate for the next-generation PON. We study the influence of wavelength interval between adjacent ONUs in OFDMA-PON by simulation and theoretical analysis, and find the minimum wavelength intervals which are different in ideal and actual system. The ideal minimum wavelength interval is twice of OFDM symbol bandwidth, while actual minimum interval is larger than that.
