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.
Some other causes of peripheral neuropathy may include: 1  Autoimmune disorders: Diseases in which the immune system attacks the bodyâs own tissues can lead to nerve damage. 2  This can include disorders such as systemic lupus erythematosus, SjoegrenâsjÃ¶gren, s rheumatoid, arthritis.  etc Disorders of the bone marrow: Peripheral neuropathy may also be caused by lymphoma, disorders that include abnormal protein in the blood, some forms of bone cancer, and amyloidosis (a disorder where amyloid, an abnormal protein that is usually produced in your bone marrow builds up in any tissue or organ).
