Butterfly-shaped optical cable coiling method
Figure-8, or " butterfly coil ", is a method where a rope or cable is wound from a center point, making a circle in one direction, then another in the opposite direction (forming an '8' shape), then repeating until the whole thing is coiled. Butterfly-shaped optical fiber cables are a popular type of fiber optic cable that is commonly used for data transmission in telecommunication networks. The name comes from the cross-section: a flat, wing-shaped profile with the optical fiber sitting in the center and two parallel strength members flanking it on either side. 1 PN600-PN800 swing arm type steel wire active pay-off rack The frame is a cabinet frame structure; it is driven by an AC frequency conversion controller, and a. see Figure 1 to Figure 6, a butterfly-shaped lead-in optical cable, which has a butterfly-shaped lead-in part 1, two spliced parts 2, and two insulated power lines 3, and the insulated power lines 3 are composed of a conductor 31 and an insulating layer 32 covering the conductor 31; It is.
