GYFTY Stranded Loose Tube Cable with Non-metallic Central Strength Member

In the GYFTY cable, single-mode/multimode fibres are positioned in the loose tubes, which are made of high modulus plastic materials, while the loose tubes strand together around non-metallic central strength member (FRP) into a compact and circular cable core. For certain high fibre count cables, the strength member would be covered with polyethylene (PE). The water-blocking materials are distributed into the interstices of the cable core.Then the cable is completed with a PE sheath.

Packing Material:

Non-returnable wooden drum.
Both ends of the fiber optic cables are securely fastened to the drum and sealed with a shrinkable cap to prevent ingress of moisture.
• Each single length of cable shall be reeled on Fumigated Wooden Drum
• Covered by plastic buffer sheet
• Sealed by strong wooden battens
• At least 1 m of inside end of cable will be reserved for testing.
• Drum length: Standard drum length is 3，000m±2%;

Cable printing:

The sequential number of the cable length shall be marked on the outer sheath of the cable at an interval of 1meter ± 1%.

The following information shall be marked on the outer sheath of the cable at an interval of about 1 meter.

1. Cable type and number of optical fiber
2. Manufacturer name
3. Month and Year of Manufacture
4. Cable length

Drum marking:

Each side of every wooden drum shall be permanently marked in a minimum of 2.5~3 cm high lettering with the following:
