5.  PACKING AND DRUM


5.1 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
