The bottom of the knowledge of the fiber optic cable

Underwater cable is laying in the bottom across rivers, lakes and beach shore of the place such as optical cable. This kind of layout of fiber optic cable than environment, pipe laying, the poor condition of directly buried installation. Underwater cable must use steel wire or steel tape armored structure, security layer structure according to the hydrogeological situation river comprehensive consideration. For example in the rocky soil, flushing sex strong seasonal river, fiber optic cable suffer wear, of the high tension, not only need crude steel wire armoured do, even with a double armoured. Also according to the construction method of water depth, width, the river flow velocity and flow velocity, river beds and river soil status of selected.

The bottom of the fiber optic cable laying environment conditions than buried cable is much more serious, repair fault technology and measures also much more difficult, so the water for the reliability requirements of fiber optic cable than buried cable high.

Undersea optical cable is also underwater cables, but laying environment conditions than general underwater cable more serious demand higher, undersea fiber optic cable system and its components to the service life of the requirements in the 25 years or more.
