what is GYFTY53 fiber optic cable
GYFTY53 is a direct-burial fiber optic cable featuring a non-metallic strength member, dual PE sheathing, and corrugated steel tape armor. Its construction is specifically designed to withstand harsh underground environments while ensuring reliable signal transmission.
The non-metallic strength member removes the risks of electromagnetic interference and corrosion, making the cable well-suited for deployment near power lines or in areas with strong electromagnetic fields. The dual PE sheath delivers enhanced protection against moisture penetration, abrasion, and environmental stress, maintaining stable performance even in wet or chemically aggressive soil. The corrugated steel tape armor further reinforces the cable mechanically, effectively shielding it from rodent attacks, crushing forces, and other physical hazards typical of direct burial installations.
Thanks to this combination of design features, GYFTY53 provides excellent resistance to electromagnetic interference, moisture, and rodent damage, making it a reliable solution for outdoor and underground fiber optic network deployments.

Product Structure & Composition
Central strength member: A non-metallic FRP (Fiber Reinforced Plastic) rod.
Loose tubes: Placed around the central strength member, each tube contains 250 μm colored fibers filled with water-resistant fiber jelly.
Cable core filling: The interstices between tubes are filled with cable jelly, and a water-blocking material is wrapped around the core to ensure full water resistance.
Inner sheath: A thin Polyethylene (PE) inner sheath applied over the cable core, also filled with jelly‑like compound for water protection.
Corrugated aluminum tape: Wrapped around the inner sheath to enhance moisture-proofing.
Water-blocking material: Applied further to prevent water ingress.
Corrugated steel tape armor: Provides crush resistance and rodent protection.
Outer sheath: A final PE outer sheath completing the cable.

Engineering Applications GYFTY53 Armored Cable
1. Aerial Installation
Installed on telephone poles or power towers. The FRP non-metallic strength member ensures stable signal in high EMI environments; dual sheathing + steel tape armor resists wind vibration and impacts.
2. Direct Burial
Buried directly in trenches with warning tape. Steel tape armor + double PE sheaths provide excellent moisture resistance, crush resistance, rodent protection, and chemical resistance.
3. Duct Installation
Pulled through pre-installed conduits or tunnels. The armored structure protects against abrasion and rodent bites; full-core water blocking adapts to wet duct environments.
4. High‑Voltage & Lightning‑Prone Areas
Used in substations, high‑voltage corridors, and frequent lightning zones. The all‑dielectric (FRP) central member eliminates conductive parts, preventing induced currents and lightning damage.

Frequently Asked Questions & Quick Inquiry
GYFTY53 Armored Cable FAQ
What is GYFTY53 fiber optic cable and what does its model name mean?
GYFTY53 is an outdoor, non-metallic strength member armored fiber optic cable. The model follows Chinese national standards: G stands for outdoor communication cable, Y for polyethylene (PE) sheath, F for non-metallic strength member (FRP – fiber reinforced plastic), T for filled loose tube stranding, 53 for double sheath structure (inner PE + steel tape armor + outer PE).
What are the typical installation scenarios for GYFTY53 cable?
GYFTY53 is suitable for direct burial, duct, and aerial installations. It is widely used in subways, tunnels, long-haul communications, and inter-office links, especially in high lightning areas, high-voltage transmission corridors, and strong electromagnetic interference environments. Its non-metallic central strength member (FRP) makes it non-conductive, allowing safe aerial use in lightning-prone regions.
What are the key features and advantages of GYFTY53 cable?
Key advantages include: excellent anti-EMI and lightning protection thanks to the non-metallic FRP central member; high crush resistance and water tightness from the double sheath plus steel tape armor (PSP); full-section water-blocking design and special gel-filled loose tubes for superior moisture protection; UV resistance and rodent resistance from dual PE sheaths; and a typical service life of over 30 years.
What are the main technical parameters of GYFTY53 cable?
Technical parameters: operating temperature range -40°C to +70°C; allowable tensile strength – long term 1000N, short term 3000N; crush resistance – long term 1000N/100mm, short term 3000N/100mm; bending radius – static 12.5×cable diameter, dynamic 25×cable diameter; fiber core count from 2 to 144 cores.
What installation precautions should be taken for GYFTY53 cable?
During installation: dynamic bending radius must not be less than 25×cable diameter, static not less than 12.5×cable diameter; short-term pulling force ≤3000N, long-term ≤1000N; installation temperature between -15°C and +60°C; pulling tension ≤1500N, speed ≤15m/min, avoid sharp 90° bends; the armor layer must be grounded at one end with grounding resistance ≤4Ω.
What is the difference between GYFTY53 and other models like GYTA or GYTS?
The main difference lies in armor materials: GYTA uses aluminum tape armor, GYTS uses steel tape armor – both typically require an additional conduit for direct burial. GYFTY53 uses a non-metallic FRP strength member + double-sheath steel tape armor, allowing direct burial without extra conduit. It also offers a wider temperature range (-40°C to +70°C) and is ideal for lightning-prone and high-EMI areas. GYTA53, another double-sheath double-armored model, can also be directly buried but includes metal components.
