Hard-clad silica optical fiber

Hard-clad silica (HCS) or polymer-clad fiber (PCF) is an optical fiber with a core of silica glass (diameter: 200 µm) and an optical cladding made of special plastic (diameter: 230 µm). In contrast to all-silica fiber, the core and cladding can be separated from each other.
