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. GYDTA / GYDTS: The protection by aluminum or steel tapes, suitable for direct burial or ducts. GYDGA: The all-dielectric (instead of metallic), provides protection in EMI-sensitive areas and can also. 3 optical cable as an example to talk about the naming of commonly used optical cable models. It incorporates 4, 6, 8, or 12-core fiber ribbons housed in a loose tube made of high-modulus material, ensuring excellent mechanical strength and resistance to hydrolysis. 4 decibels per kilometer (dB/km) at the standard operating wavelength of 1310 nanometers (nm), and a and a maximum attenuation of 0.
