Multi-core fiber switch technology for SDM network

Abstract

Space division multiplexing architecture based on multi-core fiber (MCF) is a promising solution for rapid traffic growth beyond 5G. We proposed and demonstrated a compact, high-performance, and economical 1×8 core selective switch with a 19-core MCF. A tilt-mirror-type 2D-MEMS array was deployed owing to its low optical loss, broad bandwidth, and scalability. The measured insertion loss of the fabricated device was from 0.8 to 4.0 dB. We also demonstrated a core selector and tap monitor for building a high-performance MCF-based ROADM configuration.
