Evaluation of Macrobend Loss on Long Distance Optical Ground Wire

摘要

Bend loss is a kind of loss that contributes to the power attenuation which is caused by the bending of optical fiber. For long distance optical fiber, bending might occur at joining point as there are many joining points along the link. Studies related to bend loss always relate the effect of bend radius on bend loss value. There is no study that relates the value of loss that can be affected by other factors like the natural environmental conditions. In this study, the evaluation of bend loss on existing long distance Optical Ground Wire (OPGW) was studied since the cable was exposed to any climate condition.
