Description
The GYFTZY optical cable delivers high performance and reliability in demanding environments. Its colored optical fibers are housed in high-modulus loose tubes for superior mechanical strength and hydrolysis resistance. Thixotropic gel filling ensures effective water blocking, protecting fibers from moisture and harsh conditions.
A central strength member (non-metallic FRP or metal) provides robust tensile support, while the stranded loose tubes and fillers create a compact, circular structure. Water-blocking gel fills the core gaps for added moisture resistance, and a flame-retardant outer sheath enhances safety for outdoor or high-risk installations.
Feature
Cross-section Diagram
-
Hydrolysis-Resistant Loose Tubes: High-modulus material ensures long-term durability.
-
Thixotropic Gel Protection: Seals fibers against moisture and environmental damage.
-
Flame-Retardant Sheath: Meets fire safety standards for sensitive environments.
-
Non-Metallic Strength Member (FRP): Eliminates EMI, ideal for interference-prone areas.
-
Wide Temperature Tolerance: Reliable performance under extreme conditions.
Application Scenario
-
Urban Networks: Backbone/distribution lines with fire-safe compliance.
-
Rural/Suburban Deployments: Lightweight yet durable for long-distance links.
-
Smart Cities: Public Wi-Fi, traffic monitoring, and IoT connectivity.
-
Coastal/High-Humidity Zones: Water-blocking design resists moisture and salt corrosion.
-
Tunnels/Underground: Flame-retardant for confined spaces.
-
High-EMI Areas: Non-metallic core avoids interference near power lines.
-
Emergency Networks: Critical for disaster recovery and public safety systems.
