    Abstract: Bending losses of power in a single mode step index optical fiber due to macro bending has been investigated for a wavelength of 1550nm. The effects of bending radius (4-15mm, with steps of 1mm), and wrapping turn (up to 40 turns) on loss have been studied. Twisting the optical fiber and its influence on power loss also has been investigated. Varia... Show More

    Abstract: Now a day, Adolescent sexual activity, unintended pregnancy, unsafe abortion has become a major issue in Ethiopia. Low levels of use and high unmet need for LARC have led to high levels of unintended pregnancy in Ethiopia. Use of LARC methods are good options for youth to prevent unintended pregnancies and abortions and saves their lives but studie... Show More
