Abstract
The present invention relates to a flexible high density optical fiber cable (100) having no central strength member. Particularly, the optical fiber cable (100) comprises a core having a plurality of bundled optical fiber ribbons (104), a inner layer (108), a outer layer (112) and a continuous strength layer (110) sandwiched between the inner layer (108) and the outer layer (112). The continuous strength layer (110) is a stiff strength member providing flexibility and strength to the optical fiber cable (100). The proposed structure of the optical fiber cable (100) enables the optical fiber cable (100) to have an optimized blowing performance and anti-buckling characteristics.
