Advantages of GYXTW Fiber Optic Cable

• Excellent water blocking layer, with good impermeability

• The outer sheath of steel tape is bonded and metal reinforced leading to excellent tension performance

• The central design of the beam tube minimizes the impact on the optical fiber

• Small outer diameter, lightweight, convenient construction

• Stable fiber excess length control

• After the cable is formed, the additional attenuation of the GYXTW fiber optic cable is almost zero, and the dispersion value does not change

• Adapt to most environment

Packaging

The outdoor fiber optic cable is wound on a non-returnable wooden drum. Both ends of the cable are securely fastened to the 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%.

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
