Optical fiber ribbons are applied in GYDTA to enhance the fiber density, which make it possible to produce high count fiber cable with relatively small diameter. Loose tubes are made of high modulus plastic and filled with filling compound to protect optical fiber ribbon. Loose tubes (and filler rod) are stranded around the metallic central strength member to form a compact and circular cable core, and the gap in the cable core is filled with water blocking compound. For some sizes of optical cable, the central strength member is covered with a layer of cushion. Polyethylene sheath is extruded after longitudinal wrapping of aluminum-plastic composite tape to provide the cable the ability of moisture-proof.

1、The optical fiber ribbon structure is conducive to rapid connection and shortens the installation period.
2、Reasonable design, precise control of excess length of fibers in the loose tube and optimum cabling process provides the cable excellent mechanical and environmental properties.
3、The SZ-stranded, loose tube design isolated fibers from installation and environmental rigors.
4、The water blocking gel filled core design provides the cable excellent water-proof performance and moisture-resistance.
