Direct Burial GYFTY53 Duct 6 Strand Armored Fiber Optic Cable Anti-Rodent
Description
The cable design consists of fibers housed within a flexible tube made of high-strength plastic, filled with a
water-resistant compound. At the core, a fiber reinforced plastic (FRP), sometimes coated with polyethyle-
ne (PE) for higher fiber counts, serves as a dielectric strength member. Surrounding this member, tubes and
fillers are stranded to form a compact circular core. To shield against water ingress, the cable core is filled
with water-blocking tape and covered by a thin PE inner sheath. Following this, a PSP layer is longitudinally
applied over the inner sheath, completing the cable with a protective PE outer sheath.
Application
★ Built for outdoor distribution and direct burial, ensuring resilience in various environments.
★ Optimized for trunk power transmission systems, enhancing energy transfer efficiency.
★ Ideal for access and local networks in areas with high electromagnetic interference, ensuring reliable connectivity in challenging settings.
Characteristic
★ Strong mechanical properties and resilience to varying temperatures.
★ Hydrolysis-resistant high-strength loose tube design.
★ Specialized tube filling compound for critical fiber protection.
★ Balanced crush resistance and flexibility for versatile use.
★ Complete cable core filling with loose tube filling compound.
★ PSP layer enhances moisture resistance, bolstering overall protection.
