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.

      The fibers are positioned in a loose tube made of PBT. The tubes are filled with a water-resistant filling compound. A steel wire or FRP is located in the center of the core as a metallic strength member. The tubes and the fillers are stranded around the strength member into a compact and circular core. An Aluminum Polyethylene Laminate (APL) or steel tape is applied around the cable core, which is filled with filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE (LSZH) outer sheath.(WITH DOUBLE SHEATHS)

      A bundle of micro- or mini-tubes with strengthened wall thickness is encased in a single thin HDPE sheath, forming a duct assembly specifically engineered for fiber optical cable deployment. This robust design enables versatile installation—either retrofitted into existing ducts or directly buried underground—supporting seamless integration into fiber optical cable networks. The micro ducts are optimized for high-efficiency fiber optical cable blowing, featuring an ultra-smooth inner surface with low-friction properties to minimize resistance during air-assisted cable insertion. Each micro duct is color-coded per Figure 1, facilitating quick identification and routing of fiber optical cable types (e.g., single-mode, multi-mode) during network installation and maintenance.

      Optical splice closures are used to distribute, splice, and store the outdoor optical cables which enter and exit from the ends of the closure. There are two connection ways: direct connection and splitting connection. They are applicable to situations such as overhead, man well of pipeline, embedded situation etc. Comparing with terminal box, the closure requires much stricter requirement of seal. Sealing ring and air valve are required for closure, but that are not necessary for terminal box.
