Multi-core fiber technology for optical-access and short-range links

Abstract

To provide high-capacity/high-reliability optical-access and short-range links, a novel failure-recovery system utilizing protection optical switch units and multi-core fibers was developed. Configuring the proposed failure-recovery system, the developed multi-core fiber (MCF) connection technology (i.e., fan-in/-out modules and MCF connectors) and a protection optical-switch unit experimentally demonstrated automatic impairment-aware optical-switching.
