Abstract

A passive optical network (PON) protection scheme is needed to ensure the system reliability required for business use, as PON is based on sharing a single fiber via an optical distribution network. Protection switching time is an important factor for business applications because it defines the service outage duration when a failure occurs. In this paper, we propose a PON protection scheme that enables the service outage duration to be reduced. We demonstrate Type B protection for a time and wavelength division multiplexed PON system and discuss the service outage duration.
