In future optical label switching (OLS) network, optical layer routing loop control is crucial for maintaining the network stability. In this paper, an optical loop control scheme using optical time to live (TTL) count down is proposed and experimentally demonstrated for the first time. Asynchronous TTL count-down up to 24 bits for 20-Gb/s packets is demonstrated.
