¡¡¡¡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.
