1.7  Life Time

Optical fiber cables supplied in compliance with the specifications can be capable of withstanding the typical service condition  for a period of twenty-five (25) years without detriment to the transmission or operation and maintenance characteristics of the cable.  

 

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.

Geometrical, optical, and mechanical characteristics of fiber in cable as the following table:

4.  Cable Sheath Marking

Unless otherwise specified, the cable sheath marking shall be as follows:

Ø Color: white

Ø Contents: FCJ GROUP, the year of manufacture, the type of cable, length marking

Ø Interval: 1m

5.1  Reel Length

Standard reel length: 2/4/6  km/reel

5.2  Cable Drum

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.
