Space-division multiplexing technology based on multi-core fiber and few-mode fiber in passive optical networks

摘要

We review space-division multiplexing passive optical networks (SDM-PONs) based onmulti-core fibers (MCFs) and few-mode fibers (FMFs). We compare and analyze the characteristics interms of MCFs and FMFs used in PONs. A scheme of MCF based SDM-PON with colorless ONUswithout any signal processing technology is demonstrated, thereby achieving a low cost and makingthe system design much easier.
