Polling Algorithm for Dynamic Bandwidth Distribution in LR-PON

With the advances in optical technology, long-reach PON increased the span of a broadband access network using PON technology from today's standard of 20 km to 100 km or higher. This technology can enable broadband access for a large number of customers in the access/metro area. In LR-PON the propagation delay between the telecom Central Office (CO) and the end user is increased by a very significant amount. Dynamic bandwidth allocation algorithms in traditional PON may not be sufficient due to long distance between CO & end users in LRPON.
