Recovery Scheme through Protection Switching in Neighbouring-Line Sharing for Fibre-To-The-Home Application

Abstract

Optical-fibre line failure is a significant problem that must be addressed due to the many demands of high-capacity data access. Here, we propose a novel protection method for switching devices with neighbouring-line sharing using a proposed recovery scheme. We also developed and investigated this recovery scheme for Fibre-to-the-Home (FTTH) technology application. A protection-switching device called a Customer-Access Protection Unit (CAPU) is a reliable optical-protection switching module that is included in smart and controllable FTTH networks. The CAPU provides a platform for the customer to perform fast self-restoration at their home. The approach used is based on protection switching within a network system to protect against fibre failures in the drop region. A comparison of the simulation and experimental results shows the developed protection-switching scheme was successful. Performance comparisons between the analytic methods (experimental and simulation) showed only small deviations of the value were found.
