摘　　要：Optical frequency shift keying （FSK） homodyne detection utilizing image rejection in FSK/amplitude shift keying （ASK） re-modulation wavelength-division-multiplexed passive optical network （WDM-PON） is proposed and demonstrated. Image rejection is adopted to achieve better performance. We show the result in back-to-back and 40-km distance respectively and apparent improvement is obtained in the latter situation by using image rejection. Several factors which affect the image rejection receiver are analyzed in order to find out the optimum parameters. Result shows that the presented scheme is suitable for super long reach access network, especially for future metro access network.Optical frequency shift keying （FSK） homodyne detection utilizing image rejection in FSK/amplitude shift keying （ASK） re-modulation wavelength-division-multiplexed passive optical network （WDM-PON） is proposed and demonstrated.
