The maximum reach of the Dense Wavelength-Division-Multiplexed Passive Optical Network (DWDM-PON) system can be severely limited by chromatic dispersion (CD). This paper contains the investigation of long-reach high speed 16-channel DWDM-PON system with efficient CD compensation methods. It is shown that chromatic dispersion compensation has a crucial role for guaranteed downstream optical link performance and maximum link length of high speed long-reach DWDM-PON system. The results show that usage of additional 7 km long dispersion compensating fiber (DCF) placed in central office improves the DWDM-PON network reach by 19.3% (from 57 km up to 68 km) but usage of fiber Bragg grating (FBG) improves network reach up to 26.3% (from 57 km up to 72 km). As a result, authors recommend the use of FBG for chromatic dispersion compensation to increase the maximum transmission distance of high speed DWDM-PON system.
