Corning central tube cables with smooth steel tape armoring and two steel wires are designed for outdoor use for campus, city and intercity backbones in duct and direct burial installations. The central tube cable construction, by isolating the fibers from installations and environmental rigors, provides stable and highly reliable transmission parameters. The fibers are colour coded for quick and easy identification. The cable construction, based on a central buffer tube, is very compact, light, flexible and ideal for connections requiring a moderate fibre count. These cables are designed for installation in conduits, ducts and for direct burial. Features and Benefits Waterblocking technology Outside Plant (OSP) applications UV and microbe resistant Can be directly buried or installed in ducts Corrugated steel armouring Rodent, mechanical protection and direct buried applications Small diameter and bend radius Easy installation in space-constrained areas Fibres colour coding to Telcordia-Bellcore Easy identification of the individual fibresy0q_易采办IT资料库_【易采办官网】
