Loose Tube Stranded Non-Metallic Strength Member Armored Optical Cable (GYFTA53)

The GYFTA53 optical cable consists of 250µm fibers placed into loose tubes made of high-modulus material, with the tubes filled with water-blocking compound. The center of the cable core is a non-metallic strength member (FRP); for certain fiber counts, a layer of polyethylene (PE) is extruded over the strength member. The loose tubes (and fillers) are stranded around the central strength member into a compact and circular cable core, with water-blocking filling in the interstices. The core is wrapped with aluminum-plastic laminated tape (APL), extruded with a polyethylene inner sheath, wrapped with double-sided coated steel tape (PSP), and finished with an extruded polyethylene outer jacket.

Standards

YOFC GYFTA53 optical cable complies with YD/T 901 and IEC 60794-1 standards.

Features

Excellent mechanical performance and temperature characteristics
The loose tube material itself has excellent hydrolysis resistance and high strength
The tubes are filled with special jelly for critical protection of the fibers
Good crush resistance and flexibility
The following measures are adopted to ensure the waterproof performance of the cable:

- Single non-metallic central strength member

- Loose tubes filled with special water-blocking compound

- Fully filled cable core

- Aluminum-plastic laminated tape (APL) moisture barrier

- Double-sided coated steel tape (PSP) improves the moisture penetration resistance of the cable

- Excellent water-blocking material prevents longitudinal water penetration
