翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Material dispersion coefficient ： ウィキペディア英語版 Material dispersion coefficient In an optical fiber, the material dispersion coefficient, ''M''(λ), characterizes the amount of pulse broadening by material dispersion per unit length of fiber and per unit of spectral width. It is usually expressed in picoseconds per (nanometre·kilometre). For many optical fiber materials, ''M''(λ) approaches zero at a specific wavelength λ0 between 1.3 and 1.5 μm. At wavelengths shorter than λ0, ''M''(λ) is negative and increases with wavelength; at wavelengths longer than λ0, ''M''(λ) is positive and decreases with wavelength. Pulse broadening caused by material dispersion in a unit length of optical fiber is given by the product of ''M''(λ) and spectral width (Δλ). ==References== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Material dispersion coefficient」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
