Superior reliability and ruggedness make REALTRON FC Glass/Glass/Polymer (GGP) fiber optic cable assemblies ideal for applications requiring tight bends, durability and dependability. The glass cladding around the core is reduced in size and is surrounded with a permanent and protective polymer coating, resulting in a standard 125um fiber diameter to provide a quality connection to standard fibers by mechanical splices. Moreover, the permanent polymer coating on the GGP fiber protects the glass from the environment as well as from nicks and scratches that commonly occur during handling and to provide much longer lifetime (> 200 times) than other standard fibers.
