GFYTY53 Optical Cable – Product Specification Sheet
Product Overview
The GFYTY53 Optical Cable is a stranded loose tube, non-metallic strength member armored optical cable designed for outdoor deployment in demanding environments. Engineered with a dual polyethylene (PE) sheath and corrugated steel tape armor, this cable delivers exceptional mechanical protection, moisture resistance, and crush resistance for long-term reliability in direct burial, duct, and aerial installations. Available in fiber counts ranging from 2 to 144 cores, the GFYTY53 supports both single-mode and multimode fiber types, making it a versatile solution for telecommunications infrastructure worldwide.
Construction & Design
The GFYTY53 Optical Cable cable features a sophisticated multi-layer construction engineered for durability:
Optical Fibers: 250μm fibers are positioned within high-modulus plastic loose tubes.
Water-blocking: Each loose tube is filled with a water-resistant filling compound, and the cable core is 100% filled with jelly to prevent water ingress.
Central Strength Member: A Fiber Reinforced Plastic (FRP) rod serves as the non-metallic central strength member, providing high tensile strength while eliminating electromagnetic interference concerns.
Armoring: A corrugated steel tape (PSP) is longitudinally applied over the inner sheath, delivering superior crush and rodent resistance.
Dual Sheath: The cable is completed with an inner PE sheath and an outer PE sheath, offering double protection against moisture and environmental stress.
Key Applications
The GFYTY53 Optical Cable optical cable is suitable for a wide range of outdoor and backbone infrastructure scenarios:
Long-distance backbone networks – reliable transmission over extended distances
Metropolitan area networks (MAN) and urban ring networks
Access networks & FTTx deployments – Fiber to the Home/Building/Curb
Direct burial – excellent crush resistance enables underground installation without additional conduit protection
Duct and aerial installations – flexible deployment options
High-voltage areas & lightning-prone regions – non-metallic FRP strength member provides superior anti-electromagnetic performance

FAQ
Q1: What is the difference between GFYTY53 and GYTY53?
A: The key difference lies in the central strength member. GFYTY53 uses a non-metallic Fiber Reinforced Plastic (FRP) strength member, offering superior anti-electromagnetic interference performance. GYTY53 uses a steel wire strength member. For high-voltage areas or lightning-prone regions, GFYTY53 is the recommended choice.
Q2: What types of fibers are compatible with GFYTY53 cable?
A: GFYTY53 supports both single-mode fibers (G.652D, G.655) and multimode fibers (50/125μm and 62.5/125μm). This flexibility allows the same cable model to be used across different network architectures.
Q3: Can GFYTY53 be installed directly buried without conduit?
A: Yes. The steel tape armor and dual PE sheath provide excellent crush resistance (up to 3000N/100mm) and rodent protection, making GFYTY53 specifically designed for direct burial applications.
Q4: What is the maximum pulling tension during installation?
A: The short-term tensile strength is 3000N, and the long-term tensile strength is 1000N. During installation, the bending radius should not be less than 20 times the cable diameter (20D).
Q5: Is GFYTY53 suitable for use in high-voltage environments?
A: Absolutely. The non-metallic FRP central strength member makes GFYTY53 an ideal choice for high-voltage areas, lightning-prone regions, and electromagnetic interference-sensitive locations. The dual sheath construction also provides excellent moisture protection in outdoor environments.
GFYTY53 optical cable combines rugged mechanical protection with superior optical performance, delivering a reliable, future-proof solution for modern telecommunications infrastructure.
