暗光纖

暗光纖
暗光纖 Dark fiber
暗光纖指的是已經(jīng)鋪設(shè)但是沒有投入使用的光纜。很多時候通信公司會鋪設(shè)多余其需求的光纖數(shù)量，以適應(yīng)將來的需要而避免反復(fù)的光纖鋪設(shè)帶來的高額成本。暗光纖可能被租用給個人或者其他公司，用于在他們自己的場所之間建立光連接。在這種情況下，光纖既不受電信公司控制也沒有連接到電信公司，而是由公司或者個人提供必要的設(shè)備使得其正常運(yùn)作。
Dark fiber refers to unused fiber-optic cable. Often times companies lay more lines than what&＃39;s needed in order to curb costs of having to do it again and again. The dark strands can be leased to individuals or other companies who want to establish optical connections among their own locations.
In this case, the fiber is neither controlled by nor connected to the phone company. Instead, the company or individual provides the necessary components to make it functional.
