Scattering is the primary loss mechanism offiber and the light scattered back to the OTDR provides the mechanism for OTDRtesting. The backscatter coefficient is a result of two major fiber characteristics, corediameter (or more correctly, mode fill in the core) and the material itself.
1 Cancers-peripheral neuropathy can occur in people with some cancer E.G: lymphoma and multiple myeloma. 2  Alcohol excess-high alcohol levels in the body cause nerve damage. 3  Chronic kidney disease-if the kidneys are not functioning normally, an imbalance of salts and chemicals can cause peripheral neuropathy.
