4 6 8 12 24 48 Core GYTC8S Figure 8 Self Supporting Fiber Optic
Cable
Description
In the construction of this cable, the fibers are arranged within a
loose tube crafted from high modulus plastic.
To enhance water resistance, the tubes are filled with a
specialized water-resistant compound. Acting as a c-
entral strength member, a steel wire is positioned within the core.
The tubes, along with fillers, are stranded
around the strength member to form a compact and circular cable
core. Following this, a Polyethylene (PE)
sheath is applied around the cable core, along with stranded wires
serving as support. The final result is a figure
8 structure, making this cable particularly suitable for
self-supporting aerial installations.
Application
1 Suitable for Aerial and Pipeline Laying Method: Designed to be
used effectively in both aerial and pipeline
installation methods, offering versatility in deployment.
2 Adopted for Outdoor Distribution: Tailored for outdoor
distribution scenarios, ensuring resilience and perfo-
rmance in varied environmental conditions.
3 Ideal for Long-Distance and Local Area Network Communication:
Well-suited for both long-distance and local
area network communication, providing reliable connectivity for
diverse communication needs.
Characteristics
* Good Mechanical and Temperature Performance: Demonstrates
reliable mechanical strength and temp-
erature resistance, ensuring durability in various conditions.
* High Strength Loose Tube with Hydrolysis Resistance: The cable
incorporates a high-strength loose tube
designed to resist hydrolysis, enhancing its longevity and
performance.
* Special Tube Filling Compound for Fiber Protection: Utilizes a
specialized tube filling compound to provide
critical protection to the fibers, enhancing their overall safety
and performance.
* Crush Resistance and Flexibility: Exhibits crush resistance while
maintaining flexibility, allowing for versatility
in installation and protection against external pressures.
* PE Sheath for UV Radiation Protection: The Polyethylene (PE)
sheath serves as a protective layer, shielding
the cable from the harmful effects of ultraviolet (UV) radiation.
