Self-supporting Figure 8 Fiber Optic Cable

GYTC8A/GYTC8S

Self-supporting Figure 8 Fiber Optic Cable

The 250um fibers are positioned in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire is located in the center of the core as a metallic strength member. The tubes (and fibers) are stranded around the strength member into a compact and circular cable core. After an Aluminum (or steel tape) Polyethylene Laminate (APL) moisture barrier is applied around the cable core, this part of the cable, accompanied by the stranded wires as the supporting part, is completed with a polyethylene (PE) sheath to form a figure 8 structure. Figure 8 cables, GYTC8A and GYTC8S, are also available upon request. This type of cable is specifically designed for self-supporting aerial installation.

PACKING AND MARK

OYI cables are coiled on bakelite, wooden, or ironwood drums. During transportation, the right tools should be used to avoid damaging the package and to handle them with ease. Cables should be protected from moisture, kept away from high temperatures and fire sparks, protected from over-bending and crushing, and protected from mechanical stress and damage. It is not allowed to have two lengths of cable in one drum, and both ends should be sealed. The two ends should be packed inside the drum, and a reserve length of cable not less than 3 meters should be provided.

Loose Tube Non-metallic Heavy Type Rodent Protected

The color of cable markings is white. The printing shall be carried out at intervals of 1 meter on the outer sheath of the cable. The legend for the outer sheath marking can be changed according to the user's requests.

Test report and certification provided.
