wavelength band meaning in Chinese
波长带
Examples
- Astronomers could gain only a biased idea of the universe when they were limited to the narrow wavelength band of visible rays .
由于只能在可见光的狭窄波段内观测，天文学家关于宇宙的概念显然只能是片面的。 - The series of single - mode optical fibres for telecommunication part 3 : characteristics of an extended wavelength band dispersion unshifted single - mode optical fibre
通信用单模光纤系列第3部分:波长段扩展的非色散位移单模光纤特性 - Generally , the designed channel spacing of itu - t standard in wdm systems is from 0 . 8nm to 1 . 6nm , which is much larger than the spacing required by actual communication bandwidth . for example in lightwave transmission systems , a sghz channel occupies only 0 . 04nm at the wavelength band of 1 . 55 n m . thus , most of the bandwidth in the actual transmission systems may be wasted
Itu - t标准中wdm系统设计的信道间距为0 . 8nm - 1 . 6nm ，这远远大于实际使用的信道带宽，例如一个带宽为5ghz的信道在1 . 55 m波段只占据了约0 . 04nm的波长范围，因而导致大部分的带宽被浪费。
