When used in terms of fiber optics, cable pulling is the act of pulling cables through wires while installing fiber optic services to a building or neighborhood. Some cable pulling can be done by hand and some requires special tools of the trade such as pulling grips.
fiber optics
Spindle fibers. They help separate chromosomes during cell division by attaching to the centromeres of each chromosome and pulling them to opposite poles of the cell.

The phase where each chromosome is connected to a spindle fiber is called metaphase. During metaphase, the chromosomes align at the metaphase plate at the center of the cell, and each chromosome is attached to spindle fibers emanating from opposite poles of the cell.

Just after the nuclear membrane dissolves and once the chromosomes have cloned themselves to form two chromatids connected by a centomere. The spindle fibers then attach to each chromosome.
