Abstract

The present disclosure provides an optical fiber cable (100). The optical fiber cable (100) includes a plurality of optical fibers ribbons (102) lying substantially along a longitudinal axis (116) of the optical fiber cable (100). Further, the optical fiber cable (100) includes a first layer (104) surrounding the plurality of optical fibers ribbons (102). Furthermore, the optical fiber cable (100) includes a second layer (106) surrounding the first layer (104). Furthermore, the optical fiber cable (100) includes a third layer (108) surrounding the second layer (106). Moreover, the optical fiber cable (100) includes a fourth layer (140) surrounding the third layer (108). The first layer (104) is a water blocking tape. The third layer (108) is sandwich of water blocking material and ECCS steel tape. Moreover, the optical fiber cable (100) includes two pairs of strength members (112a-b; 112c-d) embedded inside the second layer (106).
