• PACKING AND DRUM

  1.The cable is wound on a non-returnable wooden drum. Both ends of cable are securely fastened to drum and sealed with a shrinkable cap to prevent ingress of moisture. The following information shall be marked on the outer sheath of the cable at an interval of about 1 meter.
  – Cable type and number of optical fiber
  – Manufacturer name
  – Month and Year of Manufacture
  – Cable length
  The sequential number of the cable length shall be marked on the outer sheath of the cable at an interval of 1meter ± 1%.
  5.2 Drum marking, Each side of every wooden drum shall be permanently marked in a minimum of 2.5~3 cm high lettering with following:
  – Manufacture name and logo
  – Cable length
  – Cable type and number of fibers
  – Roll way
  – Gross and net weight
