Timeslot synchronization to share bandwidth for any route in bufferless bidirectional ring networks

We are developing a future metro network based on a 10 Gigabit Ethernet Passive Optical Network system to achieve both cost-effectiveness and high reliability. We propose a timeslot (TS) synchronization method to achieve a TS from a burst mode transceiver shared between any route of arbitrary fiber length by changing both the route of TS and the TS timing on each transceiver. We show the effectiveness of proposed method in exchange TSs in a bidirectional bufferless WDM/TDM ring networks during link failure through prototype systems.
