Installation Requirements for Signal Cables

Installation Requirements for Signal Cables

  • In overhead cabling mode, route the cables in the cabinet from bottom to top. In underfloor cabling mode, route the cables in the cabinet from top to bottom.
  • Conduct a continuity test for each signal cable before installation.
  • Ensure that the signal cables to be installed are free of damage, breaks, or splices.
  • Do not bind or cross cables of the same type on different devices or boards. Otherwise, device or board replacement is affected.
  • Bind Ethernet signal cables in bundles. Ensure that each bundle contains at most 20 cables.
  • During installation, do not pull, press, or crush optical cables.
  • When binding optical cables, ensure that the turning point is not tight or twisted. Neatly bind optical cable pairs.
  • Take protective measures when laying out optical cables outside the cabinet, such as placing the optical cables in corrugated pipes or routing the optical cables along troughs. Then properly bind the optical cables with cable ties. Ensure that there are no sharp edges. Choose one of the protective pipes listed in Table A-4 as required.

  • When routing optical cables into the cabinet, ensure that the length of the corrugated pipes wrapping the optical cables does not exceed 100 mm (3.94 in.). Use insulation tapes to cover the cut edges of corrugated pipes, and securely bind corrugated pipes, as shown in Figure A-12.
