摘　　要：This letter presents a low cost solution for wavelength division multiplexed orthogonal frequency division multiplexed passive optical network （WDM-OFDM-PON） with widely tunable optical filter and linear small form-factor pluggable （SFP） module. With 9-nm tunable range from 1551 to 1560 nm, the tunable filter can support up to 10-channel 100-GHz spacing WDM PON system. A linear avalanche photodiode （APD） based SFP＋ module is designed for optical OFDM signal demodulation, which can provide better receiver performance compared with limiting APD module. Experimental results show that -34 dB power budget can be achieved in 4x5-Gbps WDM-OFDM-PON system, which can satisfy the transmission requirements of next generation PON system.This letter presents a low cost solution for wavelength division multiplexed orthogonal frequency division multiplexed passive optical network （WDM-OFDM-PON） with widely tunable optical filter and linear small form-factor pluggable （SFP） module.
