Abstract

本申请提供一种介质传输线及网络设备，其中，该介质传输线包括截面为圆形的线芯、依次包覆于所述线芯外周面的线芯包层、支撑层和金属屏蔽层，并且所述支撑层支撑于所述线芯包层与所述金属屏蔽层之间，所述线芯包层、支撑层和金属屏蔽层的截面均为圆形且与线芯的圆形截面为同心圆；所述线芯、线芯包层和所述支撑层的介电常数依次减小，并且所述介质传输线主模的最大截止波长小于所述金属屏蔽层的内径。本申请实施例所述的介质传输线在线芯包层与金属屏蔽层之间设置介质常数位于金属屏蔽层与线芯包层之间的支撑层，使电场分布更加集中于介质传输线的线芯和线芯包层部分且线芯上最大，进而减小介质传输线在网络设备中的传输损耗。
