海底光纜是怎么鋪設的,怎么維護

發布時間:2017/4/21 丨 文章來源:admin 丨 瀏覽次數:3473

海底光纜是如何鋪設的,如何保護,海底光纜有專門的鋪設船以及駁船,在靠近岸邊時假定水位比較淺則有小舟擔任,否則都是那些幾十萬噸的大船的。

  船不斷往前開,然后用水下機器人沖一個溝,將光纜放入,然后再用水下機器人把泥沙沖回去,掩蓋光纜,然后不斷前進,當需求駁接時則在船上先接完畢,然后密封,再繼續鋪設。

  如今的海底光纜悉數都為光纖的,電纜的現已很少了,并且如今鋪設的悉數都是埋進泥土里的了,就是用水下機器人沖一個溝然后放進去再埋上泥土。

  水下機器人其實是運用一個高壓水泵,將水加壓到很高的壓力噴發出去,然后沖出溝槽來的。

  至于保護,這個沒有什么保護可言,一般不需求保護,只需求守時用水下機器人勘測是不是光纜有外路即可,假定有則要經過水下機器人找到受損海底光纜的準確方位。然后將埋在海底淤泥1米分配的光纜挖出,并把它堵截。作業人員要從船上放下繩子,水下機器人把光纜和繩子系在一起,并拉出海面。

  接下來,作業人員要把備用海底光纜接上受損光纜的兩個斷點。光纜接上后,經查驗通訊正常后,就拋入海水。這時,水下機器人還要用高壓水槍把海底的淤泥沖出一條深溝,再將批改的海底光纜放進去,批改作業才告完畢

  如果斷了,用衰減檢測儀丈量就可以得到詳細方位,然后去到那撈上來,進行駁接或許別的方法,一般都是將損壞的一段切掉,換上新的一段.
