Products model：GYFTCYLoose tubes of optical fiber
Central non-metallic strength member
Stranded SZ cable core filled with gel
Outer PE sheath (Tracking resistant sheath used for voltages above 110kV)
Applications：Long distance and interoffice communication
Laying mode: Aerial
Opterating temperature: -40℃~+60℃
Features:- Low optical fiber transmission attenuation and dispersion;
- Proper design and precise control of excess length of the optical fiber in the loose tube and optimum cabling workmanship render the excellent mechanical and environmental properties;
- The compact cable design and stranded SZ structure prevent the fiber from being stressed even in adverse circumstances;
- Much water blocking gel is used outside the stength member and insode the cable core to ensure the cable's excellent water and moisture resistances;
- Excellent flexibility and bending strength of the cable;
- Due to the non-metallic structure, the cable is light in weight and easy in operation and had an execllent resistance against electromanetic interferences;
- The cable facilitates the laying mode by self-supporting and has a high tensile strength and a high environment-withstanding capacity.
