2. Optical Fiber In Cable(ITU-G657A1)
Optical properties of the SM fiber are achieved through a germanium doped silica based core with a pure silica cladding which meets ITU-T G657A1, UV curable acrylate protective coating is applied over the glass cladding to provide the necessary maximum fiber lifetime.

The cables are packed in wooden drums
The minimum barrel diameter of the drum shall be more than 30 times of the nominal diameter for armored cable, and 25 times of the nominal diameter for unarmored cable.
5.3 Labeling
The direction of rotation of the color scheme is shown by marking the clockwise and anti-clockwise ends with red and green adhesive tape respectively.
The markings are on both sides of the flanges as follows:
Ø Cable Type/Size
Ø Cable Length
Ø Gross Weight.
Ø FCJ GROUP.
Ø Shipping mark.
5.4 Cable Packing
Both cable ends are provided with protections against water penetration and firmly secured to the drum, so the cable cannot move and the turns cannot slide when it is moved, handled or laid. the inner end has at least 3 meters of accessible length to perform reception tests in the cables.
