Abstract: The present disclosure provides an optical fiber. The optical fiber includes a core region. The core region is defined by a region around central longitudinal axis of the optical fiber. In addition, the core region has a first annular region. The first annular region is defined from the central longitudinal axis to a first radius r1 from the central longitudinal axis. Moreover, the core region has a second annular region. The second annular region is defined from the first radius r1 to a second radius r2. Further, the core region has a third annular region. The third annular region is defined from the second radius r2 to a third radius r3. Also, the optical fiber includes a cladding. The cladding region has a fourth radius r4.

Abstract: The present disclosure provides an optical fiber (100). The optical fiber (100) includes a core region (102). The core region (102) is defined by a region around central longitudinal axis (112) of the optical fiber (100). In addition, the core region (100) has a first annular region (106). The first annular region (106) is defined from the central longitudinal axis (112) to a first radius from the central longitudinal axis. Moreover, the core region (102) has a second annular region (108). The second annular region (108) is defined from the first radius to a second radius. Further, the core region (102) has a third annular region (110). The third annular region (110) is defined from the second radius to a third radius. Also, the optical fiber (100) includes a cladding (104). The cladding region (104) has a fourth radius.
