Technologies for Future Optical Access Networks

The rapid growth in Internet traffic is continuing to fuel the penetration of fiber networks into the access network section. Future access networks will have to meet the ever increasing demand. Fiber to-the-home (FTTH) networks based on Passive optical networks (PONs) systems have been widely deployed to fully support “triple-play” services including data, voice, and video. Wavelength-division-multiplexing passive optical networks (WDM/PONs), which offer point-to-point connectivity via a dedicated wavelength to each customer, are expected to provide the optimum FTTH architecture. WDM-PONs are an attractive option due to their high capacity, easy management, network security, protocol and bit rate transparency, and easy upgradability. However, the network complexity and cost have been the most critical issues for the practical deployment. To overcome this problem, current research is focusing on increasing the operating speed and maximum reach (or splitting ratio) of WDM PON cost-effectively.
