Performance optimization of high capacity long reach 32 channel FTTH downstream link employing triple play services

In this paper performance of high capacity, long reach, 32 channel FTTH downstream link employing triple play services has been investigated on the performance metrics viz. eye-opening, BER and Q2 dB. DWDM has been employed for bandwidth optimization. The triple-play service is realized as a combination of data, voice, and video signals. The Internet component is represented by a data link with a high-speed of 2.5 Gb/s downstream. The voice component is represented as VOIP and then combined with data component. The video component is represented as a RF video signal. The reach of the WDM-PON system can be severely limited by chromatic dispersion. Therefore, we have employed 80 km of non-linear fiber in combination with 20 km of reverse dispersion fiber to negate the accumulated chromatic dispersion which ensures long reach of the modeled FTTH system. Investigations reveal the effective bandwidth optimization using DWDM. High ‘Q2 dB’ and low BER results confirm the feasibility of proposed high capacity, long reach FTTH link.
