  1. 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標準中wdm系統設計的通道間距為0 . 8nm - 1 . 6nm ，這遠遠大於實際使用的通道帶寬，例如一個帶寬為5ghz的通道在1 . 55 m波段只佔據了約0 . 04nm的波長范圍，因而導致大部分的帶寬被浪費。
  2. Standard for protective spacing of radio interference from over - head electric lines substations to t

    架空電力線路變電所對電視差轉臺轉播臺無線電干擾防護間距標準
  3. Pressed metal plates, the water board and the whole board should be fixed angle reliable, strong, anti - corrosion coatings and sealing material coating installation intact, connector size, spacing and the state should comply with the design requirements of the standard
