Outdoor fiber optic cable direct burial cable aluminum tape layer loose tube GYTA
Description
The fibers are housed in a high modulus plastic loose tube, filled with a water-resistant compound. A central
steel wire acts as the core's metallic strength member, around which the tubes and fillers are stranded, forming
a compact, circular cable core. An Aluminum tape, longitudinally applied and filled with protective compound,
shields the core from water ingress. Finally, the cable is encased in a durable PE sheath for overall protection.
Application
* Outdoor-focused design: Tailored for outdoor use, ensuring durability and resilience in different weather
conditions and environments.
* Versatile installation options: Well-suited for aerial setups and pipeline laying methods, offering flexibility
in deployment strategies.
* Extensive communication range: Designed for both long-distance and local area network communication,
catering to various connectivity needs across different distances and settings.
Characteristic
• Outdoor suitability: Designed for robust performance in outdoor environments, ensuring reliability and durability.
• Versatile installation compatibility: Ideal for aerial installations and pipeline laying methods, offering flexible
deployment options.
• Broad communication capabilities: Well-suited for both long-distance transmissions and local area network
connectivity, catering to diverse communication needs across varying distances and settings.
