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. Variations of macro bending loss with these two parameters have been measured, loss with number of turns and radius of curvature have been measured. This work founds that the Macro bending and wrapping turn loss increases as the bending radius and wrapping turn increases.
