Description

The guidance method of traction is stablized for optical cable
Technical field
The present invention relates to optical cable laying field, specifically refer to the guidance method stablizing traction for optical cable.
Background technology
In daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.Most optical fiber before use must be coated by which floor operator guards, and namely the cable after coated is called as optical cable, and the protective seam of fiber outer layer and insulation course can prevent surrounding environment to the injury of optical fiber, Ru Shui, fire, electric shock etc.
In the long distance process of deployment of optical cable, because the dynamics of factor optical cable when drawing of distance can increase with the increase of distance, therefore may cause being partially damaged because imposed stress concentrates in the local of optical cable, easily there is surge phenomenon in cable dish exit in the optical cable put with duration distance, the middle part of optical cable and the end of optical cable is made to occur looping, namely probably cause the bending radius of optical cable to be less than 15 ~ 20 times of its external diameter, increase the possibility of the impaired fracture of optical fiber.
