Double Armored Fiber Optic Cable: Rugged Protection for Harsh Environments
This double armored fiber optic cable is constructed with a stranded loose tube design, incorporating both corrugated steel tape and steel wire armoring for maximum protection. It features an inner PE sheath, steel wire armoring, and an outer PE sheath. This robust construction makes it ideal for harsh environments and demanding applications.
Description
HOC’s steel wire and steel tape double armored fiber optic cable offers excellent crush resistance due to its heavy armoring. The steel wire reinforcement provides superior tensile strength. The fiber optic units are protected by corrugated steel tape, steel wire, a double sheath, and a water-blocking filling compound, making it suitable for undersea communication. Its mechanical and temperature performance allows for underwater and direct buried installation.
Application
This cable is suitable for long-distance communication, inter-office communication, and various challenging installations such as steep slopes and river crossings with harsh environmental conditions.
Features
- Double armored fiber optic cable with corrugated steel tape and steel wire
- Steel wire armoring (SWA) for improved tensile and impact resistance
- Double PE sheath for excellent moisture resistance
- Corrugated steel tape surrounding the stranded loose tube unit
- Water-blocking filling compound within the loose tube
