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.
In the UK, diabetes (both type 1 and type 2) is the most common cause of peripheral neuropathy. Over time, the high blood sugar levels associated with diabetes can damage the nerves. This type of nerve damage is known as diabetic polyneuropathy. Peripheral neuropathy can also have a wide range of other causes.
