Gyts53 Fiber Optic Cable
The GYTS53 is a rugged, double-sheath, double-armored outdoor fiber optic cable, engineered for the most demanding environmental conditions . Its robust construction makes it the ideal choice for direct burial, high-crush resistance, and anti-rodent applications where standard cables would fail .
Construction and Design
The cable's core consists of single-mode or multi-mode fibers (250µm) placed within loose tubes made of high-modulus PBT plastic, which are filled with a water-resistant compound . These tubes are helically stranded around a central metallic strength member (steel wire) to provide exceptional tensile strength .
The armoring system is where the GYTS53 excels. It features:
Inner Sheath: A thin PE layer over the cable core .
PSP Armor: A corrugated steel tape (PSP) is longitudinally applied over the inner sheath, providing formidable protection against crushing and rodent attacks .
Outer Sheath: A thick, robust PE outer sheath completes the cable, offering excellent resistance to UV radiation, moisture, and soil chemicals . This dual-layer armor system ensures the cable can withstand extreme mechanical stress and harsh outdoor environments.
Key Applications & Advantages
The GYTS53 is the cable of choice for core network, metropolitan area network (MAN), and access network backbones . It is specifically designed for:
Direct Burial: The heavy armor protects against excavation damage, soil movement, and moisture ingress, with an IP68 waterproof rating .
High Rodent Resistance: The steel tape armor effectively deters rodents, a common cause of cable failure in outdoor settings .
Aerial Installation: Its high tensile strength and UV-resistant jacket allow for reliable aerial deployment .
With an operating temperature range of -40°C to +70°C and a design life exceeding 30 years, it offers unparalleled reliability for critical communication infrastructure .

FAQ
1. What is the main difference between GYTS and GYTS53 cables?
The GYTS typically has a single layer of steel tape armor (PSP) with a single PE sheath, while the GYTS53 features a double-layer protection system: an inner PE sheath, a corrugated steel tape armor, and a robust outer PE sheath. This makes the GYTS53 significantly more resistant to crushing, impact, and rodent damage for direct burial applications .
2. Is the GYTS53 cable suitable for aerial installation?
Yes, despite being optimized for direct burial, its high tensile strength (up to 3000N) and UV-resistant outer jacket make it suitable for aerial installation . However, it is heavier than dedicated aerial cables, so the supporting structures must be able to bear the additional weight.
3. What types of optical fibers can be used in a GYTS53 cable?
The cable can accommodate a variety of fibers. The most common is the standard single-mode fiber G.652D. It can also be customized with bend-insensitive fibers like G.657A1/A2 or multi-mode fibers (e.g., 50/125µm) for different network requirements .
4. What is the minimum bending radius for this cable during installation?
For safe installation, the dynamic bending radius (during pulling) should not be less than 20 times the cable's outer diameter (20D). For static applications (after installation), the minimum radius is typically 15 times the outer diameter (15D) .
5. How is the cable protected against water ingress?
The GYTS53 utilizes a comprehensive water-blocking system. The loose tubes are filled with a water-resistant filling compound, and the cable core is also filled with a filling compound. Additionally, the double sheath and steel tape armor provide an excellent physical barrier against moisture, ensuring a waterproof rating suitable for the most humid and wet environments .
