光纤简介

光通信使用的光波波长规模是在近红外区内，波长为0.8至1.8um。可分为短波长段（0.85um）和长波长段（1.31um和1.55um）。

(The wavelength scale of light waves used in optical communication is in the near-infrared region, with a wavelength of 0.8 to 1.8um. It can be divided into short wavelength band (0.85um) and long wavelength band (1.31um and 1.55um).)
