Based on radio over ifber (ROF) technique, an access system solution based on ROF-PON (passive optical network) in which O-OFDM modulation is used was proposed. Both the architecture of DWDM-PON access system based on ROF and the laser source modulation technique of ROF system were discussed. In addition, the problem of dispersion of OFDM technique applied to long-distance transmission in DWDM system was researched and corresponding solution was presented.
