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.
Peripheral neuropathy (more commonly called neuropathy) is a general term for diseases that cause damage to the nerves outside of the brain and spinal cord. While diabetes is a frequent cause of neuropathy, it is not the only cause. Nutritional deficiencies (B-12 and folate), chemical exposures, pressure on nerves, or medications (such as some of those used for chemotherapy or to treat AIDS) can also cause neuropathy.
