To meet the fast-growing bandwidth requirement of end users, a time and wavelength division multiplexing technique is proposed to extend the network capacity. Meanwhile, the data rate of each wavelength should also be increased. In this paper, the feasibility of using DML in TWDM-PON systems is investigated, with an emphasis on chirp management and power budget improving techniques. Besides, the Raman crosstalks between the new-added and the traditional channels are analyzed with a proposed crosstalk mitigation solution based on Dicode coding.
