    光缆

    光缆是什么?

    光缆是一定数量的光纤按照一定方式组成缆芯,外包有护套,有的还包覆外护层,用以实现光信号传输的一种通信线缆组件。光纤通信是现代信息传输的重要方式之一。它具有容量大、中继距离长、保密性好、不受电磁干扰和节省铜材等优点。

    光缆的分类

    • 单模光缆:适用于长距离的信号传输。它的波长是1300nm,是不可视的,对人眼有害。单模光纤的直径为9μm,由于它的直径如此之小,使用它进行长距离传送信号时,光波不易被改变。
    • 多模光缆:直径通常有50和5μm两种规格,它们之间并没有速度上的差异。多模光纤的波长范围为850nm和1300nm两种。850nm波长的光是可见的,对人眼无害。1300nm波长是不可见的,而且对视网膜有害。多模光纤使用的是一种聚集的LED而不是真正的激光。
