Customer access protection unit for survivable FTTH network

This paper describes a protection against fiber fault in fiber line which is called Customer Access Protection Unit (CAPU) that will also being placed in customer end user in order to perform as smart restoration if there is uncertainty of fiber cut occurs in distribution region. Furthermore, this paper also includes the power penalty analysis for optical switch cascaded in our network protection design according to the CAPU device. This device is expected to perform as fast protection against failure and only increase low insertion loss in each remote node (RN).
