Definition: Bephilter is a type of filter used in optical fibers for purification. It is made from a polymer that has been modified to capture and remove particulate matter, such as dust or impurities, from the fiber's core. The Bephilter works by capturing particles smaller than 10 microns (Ξm) and removing them from the fiber. This process helps in purifying optical fibers for use in optical communication systems.
