If cables, power line and grounding conductor are laid in the same channel,

When laying the pigtail, avoid knotting of optical fiber cable, minimize the
amount of turnings and avoid turnings with overly small radius. Bundle
pigtails in proper tightness and avoid too tightly bundling. If laid on a cabling
rack, it should be placed separately from other cables.
10. There must be the relevant marks at both ends of cable and the information on
the marks should be explicit to facilitate maintenance
Attention: When laying pigtails, prevent optical fiber cable from knotting, minimize the
amount of turnings and avoid turnings with too small radius, because turning with too small radius
will result in serious consumption of optical signal of links, affecting communication quality.
