The Relevant Types of GYTS Fiber Optic Cable
OUFU can customize various types of GYTS fiber optic cables for you. Please customize the GYTS fiber optic cable according to your needs.
Full water-blocking: gel-filled tubes + flooding compound + PSP for long-term moisture protection
Heavy-duty steel tape armor: crush/rodent/impact resistant for direct burial & harsh outdoor
Excellent tensile & temperature stability: -40℃ to +70℃, ideal for duct/direct burial
Universal & cost-effective: multi-installation, low maintenance, long service life
Superior Mechanical Protection Capability
The three-layer protective structure of GYTS fiber optic cable, which consists of phosphated steel wire reinforcement core, coated steel belt and outer sheath, can resist external forces such as stretching, side pressure, impact and wear. During construction, it can withstand large traction forces, and after laying, it is less likely to be compressed by external factors. It is especially suitable for scenarios such as overhead and direct burial that are prone to external influences.


Waterproof and Moisture-Proof, With High Stability
The loose jacket of GYTS fiber optic cable is filled with waterproof grease, and the cable core gap is also filled with water-blocking compounds. Combined with the steel band water-blocking barrier, a fully sealed waterproof design is achieved. This can effectively prevent water and moisture from penetrating, ensuring stable optical fiber transmission performance and avoiding the problem of increased attenuation due to moisture absorption.
High Environmental Adaptability
The PE outer sheath of GYTS fiber optic cable has excellent resistance to ultraviolet rays and aging. The optical cable can operate stably within a wide temperature range of -40℃ to +60℃, and is not affected by harsh climates such as severe cold, intense heat, sun exposure, or rain. At the same time, it is resistant to acids and alkalis and corrosion, and can meet the communication needs of special environments such as mining areas, oil fields, and coastal areas.


OUFU Offers Quality Assurance for GYTS Fiber Optic Cables
The GYTS fiber optic cable of OUFU has obtained ISO9001 certification, ISO14001 certification, product CE certification, and RoHS certification. It complies with the entry standards for both domestic and international markets and can directly handle overseas orders.

GYTS fiber optic cable are widely used in outdoor long-distance and high-capacity communication systems due to their excellent mechanical properties and environmental resistance. Their specific advantages include:
City backbone network and access network: Suitable for pipeline and overhead installations in cities.
Diverse environment projects: Suitable for mining areas, oil fields, railways, highways, and river-crossing/route-crossing projects.
Industrial communication: Suitable for industrial parks, power systems, and other scenarios with high requirements for interference resistance and stability.
The GYTS fiber optic cable supports three mainstream outdoor laying methods:
Aerial laying: It can be fixed on the poles using suspension clips and is suitable for areas where pipeline construction is difficult.
Pipe laying: It is inserted into the pre-laid underground pipes by traction, avoiding direct exposure to the external environment and reducing the risk of damage.
Direct burial laying: It is directly buried in the soil, suitable for long-distance projects in rural areas or suburbs.
It adopts a multi-layer waterproof design to ensure stable operation even in humid or water-contacting environments:
Internal waterproofing: Each loose tube is filled with waterproof paste to tightly wrap the optical cable and isolate moisture.
Cable core waterproofing: The gap between the loose tube and the filling rope is filled with waterproof compound to prevent water from penetrating along the cable core.
Sheath waterproofing: Coated steel strips are longitudinally wound to form a physical barrier, and the outer PE sheath is tightly bonded to the steel strips to block external water and moisture.
The standard number of fiber cores for GYTS fiber optic cable varies from 4 to 144, which can meet the needs of most backbone networks and access networks. For large-capacity projects, by optimizing the arrangement of the loose tubes and the design of the optical fiber cores, it can be customized to have 288 or more fiber cores.
Under standard installation and usage conditions, the service life of the GYTS fiber optic cable can reach 20 to 25 years. Its long service life is attributed to the stable loose tube structure, corrosion-resistant steel tape sheath, and UV-resistant polyethylene outer layer, which reduce the aging speed of the optical cable in outdoor environments.
The key construction precautions include:
Tension control: The maximum tension during the laying process should not exceed the product specification (usually 1500 – 2000 N of the standard specification) to avoid damaging the central reinforcement and the optical fiber circuit breaker.
Curvature radius: The minimum curvature radius during the laying process should be ≥ 20 times the cable diameter, and it should be ≥ 10 times the cable diameter after the laying is completed.
