What is GYTA Fiber Optic Cable
The GYTA cable places a 250 μm fiber in a loose sleeve made of high modulus plastic. The sleeve is filled with waterproof filler, and there is a steel wire in the center as a metal reinforcement. For high-core cables, PE is sometimes coated. The sleeve and filler are twisted around the reinforcement to form a compact round cable core. The cable core is covered with a layer of APL and filled with waterproof filler to prevent water from penetrating. Finally, the cable is completed with a PE jacket.

Структура и состав продукта
Outer Jacket (Outer Sheath)：The outermost black polyethylene (PE) sheath provides UV resistance, corrosion resistance, and abrasion resistance, protecting the optical cable from external damage in conduits, aerials, and other environments.
APL (Aluminum-Plastic Composite Tape)：This is a longitudinally wrapped double-sided plastic-coated corrugated aluminum tape that provides moisture resistance, water blocking, and certain crush resistance capabilities, and can also serve as an electrical shielding layer to prevent external electromagnetic interference.
Water Blocking Material：Located on the inner side of the aluminum tape, the water-blocking tape or yarn swells rapidly when in contact with water, blocking moisture from penetrating longitudinally along the cable and keeping the internal fibers dry.
Central Strength Member：Usually a single steel wire or glass fiber-reinforced plastic (FRP) rod, located at the center of the cable, it bears the tensile loads during installation and operation, preventing fiber breakage due to stress.
FBT Loose Tube：Here, FBT may refer to a "fiber optic loose tube" (e.g., made of PBT material). The tube loosely accommodates multiple fibers and can be filled with water-blocking material, allowing the fibers to move freely and buffering external stress.
Fiber：The core component for transmitting optical signals, generally single-mode fibers such as G.652D or G.655. responsible for low-loss, high-bandwidth data transmission.
Water Blocking Material：Here it refers to the thixotropic gel filled inside the loose tube, which suspends and protects the fibers, prevents moisture from entering the tube, and does not affect the micro-bending performance of the fibers.
Преимущества GYTA armored Fiber Optic Cable
1. Excellent mechanical and environmental protection
It offers good mechanical strength and high temperature resistance. The high-quality PE outer jacket provides effective UV protection, while the aluminum‑polyethylene laminate (APL) acts as a reliable moisture barrier.
2. Advanced fiber protection and structural design
It features a high‑strength, hydrolysis‑resistant loose tube. Special filling compounds inside the tube play a key role in protecting the optical fibers. The specially designed compact structure prevents loose tube shrinkage, ensuring long‑term stability.
Инженерные приложения GYTA armored Fiber Optic Cable
1. Highway pipeline projects
In highway electromechanical projects, GYTA cable is widely laid in underground ducts along the roadside. Its aluminum-laminated tape and moisture-blocking design protect the fibers from groundwater and soil corrosion, ensuring reliable transmission for toll stations, surveillance cameras, and traffic control systems.
2. Large-scale water conservancy
For major water diversion or irrigation schemes, GYTA cable serves as the backbone of the communication network. The cable’s resistance to side pressure and temperature variation guarantees stable data exchange between remote pumping stations, valves, and central dispatch centers, even in humid or submerged environments.
3. Overhead relocation in urban renovation
During town road upgrades or rural infrastructure projects, GYTA cable is often installed aerially on existing poles. The aluminum armor provides sufficient protection against falling debris and light impacts, while the lightweight design and fast deployment make it cost-effective for temporary or congested areas.
4. Industrial monitoring and harsh environments
In steel plants or chemical facilities, GYTA cable can be suspended on high-temperature bridge racks to carry gas or vibration sensor data. For extreme climates such as plateau railways or frozen soil regions, armored variants like GYTA53 withstand sub‑zero temperatures and mechanical stress, ensuring long‑term operation of critical communication links.

| Maintenance Difficulty | Low – corrosion resistance reduces long‑term issues; mid‑span access easier than steel armor | Moderate – heavier armor makes repairs harder; must inspect for rust at sheath damage points | Low – simple structure, easy to splice and maintain, but limited protection may lead to higher fault rate in harsh environments |
GYTA armored Fiber Optic Cable Руководство по выбору
Engineering selection between GYTA and GYTS:
GYTA uses aluminum tape armor, offering superior corrosion and moisture resistance compared to GYTS. This makes GYTA ideal for wet environments, coastal areas, or long‑term duct installation where rust is a concern. GYTS, on the other hand, uses steel tape armor, providing much higher crush resistance, better protection against rodents and bullets. It is preferred for direct burial in rocky terrain, aerial routes with high mechanical stress, or any application where side pressure is a major factor.
Flame retardancy and UV resistance considerations:
For outdoor long‑term exposure (aerial or duct), both GYTA and GYTS have PE sheaths with excellent UV resistance, but they are not flame‑retardant. They should NOT be used indoors (e.g., equipment rooms, tunnels, high‑rise buildings) unless a flame‑retardant variant (GYTZA or GYTZS) is specified. For core network entry sections (typically ≥500 m per segment) or fire‑sensitive areas, always choose LSZH‑sheathed cables (GYTZA/GYTZS) instead of standard GYTA/GYTS.
Non‑flame‑retardant cable applications:
GYTA is a classic “duct cable” – its PE sheath provides excellent UV resistance and long‑term outdoor reliability, but it burns when exposed to fire and is unsuitable for indoor fire‑rated spaces. GYXTW is the most compact and lowest‑cost option, ideal for low‑core‑count (≤24 cores) aerial or light‑duty duct installations. However, it also lacks flame retardancy and its crush resistance is limited – not recommended for direct burial or harsh mechanical environments.
GYTA Optical Cable – Installation Instructions
Minimum bending radius：During installation: 20 × cable diameter; after installation: 10 × cable diameter.
Tensile load：Maximum allowable pulling force: 1500–3000 N (depending on core count). Use a proper pulling grip to avoid stress on the fibers.
Crushing resistance：Short-term: 3000 N/100 mm; long-term: 1000 N/100 mm. Do not crush or impact the cable sharply.
Installation methods：Suitable for duct, aerial (with messenger wire), and direct burial (if additional protection is applied). Avoid sharp edges and excessive twisting.
Temperature range：Installation: –20°C to +60°C; operation: –40°C to +70°C.
Handling notes：Do not exceed the rated pulling force. Use lubricant for long duct runs. Keep the cable end sealed against moisture during and after installation.
