GYDTA is loose tube structure cable which makes the fiber good secondary excess length and allows the optical fiber free movement in the tube, this help keep the fiber stress free. The corrugated aluminum armored tape provides the proper moisture resistance for the whole cable. According to their design, ribbon optical cables are intended to have a large number of optical fibers transferred in a small volume, organized, and most efficiently. Optical cables can be divided into several categories. GYDTA (metal strengthening member, loose tube stranded and filled with optical fiber ribbon, aluminum-polyethylene bonded sheathed outdoor optical fiber cable for communication) The structure of the optical cable is to sheath the single-mode optical fiber ribbon with the inner filling made of high. The Bynet GYDTA and GYDTS ribbon fiber optic cables are engineered for high-capacity outdoor transmission systems requiring exceptional fiber density and long-term reliability. These loose tubes are filled with a water-blocking compound. For cables with specific. The structure of GYDTA optical cable involves placing fiber ribbons in a loose tube with filling gel (the fiber ribbon can be 4, 6, 8, or 12 cores); the central core of the cable is a steel wire (may be added with PE cushioning layer), surrounded by a loose tube and filled with filling rope; the.
