Abstract :
The Passive Optical Network (PON) was proposed as a solution for the bandwidth bottleneck at the Access Networks, mainly due to the characteristics of the fibers. A failure in the network causes a large quantity of information losses. By adopting a ring topology and optical switches we propose a novel protection mechanism for time division multiplexed passive optical network (TDM-PON) that provides resilience against multiple network fails without equipment duplication. Two types of rings with one and two fibers are considered.
