During the construction and positioning of optical cables, the bending radius should not be too small or form a 90 ° straight bending angle. During construction, the bending radius should be greater than the dynamic allowable bending radius specified in Table 2: during placement and positioning, the bending radius should be greater than the static allowable bending radius specified in Table 2.
