可减少系统组网所需的器件数量

提高系统集成度

降低组网成本。理论分析与实验证明

该新型WSC整体插损<5dB

50GHz栅格工作状态3dB带宽>40GHz

与理论结果基本吻合。

Abstract

This paper presents the structural design of a novel liquid crystal technology-based Wavelength Selective Cross-Connect（WSC）

which realizes 2×4flex-grid WSC by means of polarization multiplexing on the basis of the conventional 1×N WSC

thus reducing the number of the devices required for system networking

improving the system integration level and lowering the networking cost.Theoretical analysis and experimental results verify that total insertion loss of this WSC is less than5 dB and the 3dB bandwidth of 50 GHz grid in operating state is greater than 40 GHz.
