A loose tube composed of a high modulus plastic is used to hold the fiber ribbons. The interstice is filled with a water-resistant filling substance on both the inside and exterior of the tubes. Located in the heart of the core as a strength element is a fiber-reinforced plastic rod that may be coated with polyethylene if needed. The strength member is encircled by tubers (and fillers) to create a small, spherical cable core.
To create a cable, the steel tape with a plastic coating is wrapped around the core and extruded into a polyethylene sheath.
Good moisture-proof and water-resistant performance is provided by the full section water blocking structure.
Ideal optical fiber protection is provided by special filling gel-filled loose tubes.
A core strength member is a dielectric FRP rod with a high modulus.
High fiber density, cost-effective, easy to identify and maintain, and convenient for installation.
It is simple to route the flexible buffer tubes in closures.
Outstanding temperature and mechanical performance.
Superior protection against UV rays, fungi, abrasions, and other outdoor elements is offered by jackets.
A 30-year lifetime is made possible by strict workmanship and raw material management.
