AI Technical Summary
In the existing technology, relying on work experience to judge the bending range during the optical cable laying process can easily lead to damage to the optical cable. In particular, when the bending radius is too small, the optical fiber transmission conditions are destroyed and stress is concentrated, resulting in damage to the optical cable.
