optical cable in the manufacturing process,
in order to increase the tensile strength
, the wire is added in the optical cable.
when setting the connection box,
only pay attention to the optical fiber splicing.
use common methods,
the two section of the fiber optic cable,
fixed on both ends of the connecting box,
naturally form a gap.
such,
when the wire in any segment of the optical cable induces a high lightning voltage,
to the other end of the wire discharge,
the spark generated during discharge,
damage of optical fiber in the connecting box.
in order to prevent the occurrence of this phenomenon,
in the construction process of optical cable,
care should be taken to connect the cable ends in the connection box with wire.
the wire is connected with the stranded wire of the hanging cable,
this can effectively avoid the fiber optic cable was struck by lightning.
