However, at this stage it is instructive to consider the advantages provided by lightwave communication via optical fibers in comparison with other forms of line and radio communication which have brought about the introduction of such systems in many areas throughout the world
然而，相比于其它在全世界很多地區引進這樣的系統的有線及無線電通信方式來說，重視由光纖實現的光波通信的優勢是很有意義的 -
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。
