Description
The GYFY53 optical cable uses high-modulus plastic loose tubes filled with water-blocking gel to cover the fibers. Stranded loose tubes and fillers are bound together with a central non-metallic strength member (FRP). The stranded loose tubes and fillers are gel-filled for secondary protection from moisture, coated with polyethylene inner sheathing, double-sided coated steel tape, and an outer PE sheath. This multi-layer structure provides strength, water resistance, and durability outdoors in the long term.
Feature
Cross-section Diagram
- Easy splicing and fast installation.
- Lightweight cost-effectiveness eliminates handling and long-distance laying problems.
- Strong performance for wide temperature range.
- Very good crush resistance with good flexibility for change of terrain.
- Duct and aerial application.
Application Scenario
- Direct Burial: Suitable for buried use, safe from any risk of metal corrosion.
- Duct Installations: High tensile strength allows easy pulling in conduit systems.
- Moisture Areas: Water-resistance gel-filled core keeps water out in wet locations.
- EMI-Sensitive Locations: Non-metallic strength member of FRP avoids interference near power lines or manufacturing zones.
- Rural and Suburban Networks: Corrosion-free, weight light, ideal for expanded communication coverage.
- Outdoor Harsh Environment: Resistant to UV rays, temperature change, and environmental stress.
