CST Armored Fiber Optic Cable: Robust and Reliable Connectivity
Introducing the CST (Corrugated Steel Tape) armored fiber optic cable, a robust solution designed for demanding outdoor deployments. This cable provides reliable high-bandwidth connectivity with enhanced protection against physical damage and environmental factors. Its armored construction makes it ideal for direct burial and duct installations, ensuring long-lasting performance in harsh conditions.
Description
The HOC uni-tube loose tube CST cable houses optical fibers (from 4 to 288 cores) within a jelly-filled loose tube. A layer of water-blocking material, fiberglass yarn, and a corrugated steel tape (CST) wrap the central uni-tube, forming a strengthened cable core. This core is then encased in a PE or LSZH black outer sheath, providing additional protection. Customization options are available for fiber type, fiber count, cable jacket color, and sheath material (PE, LSZH, Flame-Retardant). Cable sheath printing includes length marking and other essential information.
Applications
CST armored fiber optic cable is suitable for various applications, including:
- Duct installations
- Direct burial
- Backbone communication cabling
