Aluminum-coated step index multimode silica fibers (High OH)

Aluminum-coated step index multimode optical fibers have all the benefits of silica-silica fibers. Their transmittance covers a spectral range of 250 to 1200 nm, and also remains stable in corrosive chemicals that normally react to silica glass. The temperature range is from -196oC to +400oC. Hermetically metal-coated optical fibers are the optimum candidate when used in high vacuum and harsh environmental conditions
