GYFTA53 Double Sheathed Fiber Optic Cable for Directly Underground Application
 
 
Quick Detail:

 
Description:
 
The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress.  After a corrugated steel tape armor is applied, the cable is completed with a PE outer sheath.
 
Applications:

• Adopted to Outdoor distribution. 
• Suitable for aerial duct and buried method.
• Long distance and local area network communication.

 
 
 
KT3001 GYFTA53 Double Sheathed Fiber Optic Cable for Direct Underground Applications

Description

The KT3001 GYFTA53 cable is designed for robust performance in direct underground applications. Key features include:

• Structure:
  • Fibers: 250μm positioned in loose tubes made from high-modulus plastic.
  • Filling: Water-resistant compound in tubes and jelly in the inner sheath to prevent water ingress.
  • Strength Member: Central Fiber Reinforced Plastic (FRP) as a non-metallic strength member.
  • Core Wrapping: Stranded tubes around the FRP with Aluminum Polyethylene Laminate (APL) applied for added protection.
  • Sheaths: Thin PE inner sheath and a corrugated steel tape armored outer PE sheath.

Characteristics

• Excellent mechanical and temperature performance for harsh environments.
• High-strength loose tube ensures hydrolysis resistance and fiber protection.
• Specialized tube filling compound guarantees optimal fiber protection.
• High crush resistance and flexibility for demanding applications.

 
 
The GYFTA53 fiber optic cable is designed with specific technical parameters that ensure durability and reliable performance in underground applications. The cable has a consistent diameter of 16.8 mm across its variations, with a weight of 255 kg/km. It is capable of withstanding tensile strengths of 1000 N for long-term use and up to 3000 N for short-term conditions. Additionally, it demonstrates excellent crush resistance, tolerating 1000 N/100 mm in long-term scenarios and 3000 N/100 mm in short-term situations. The bending radius is specified as 10 times the cable diameter for static conditions and 20 times the diameter for dynamic applications.
 
Regarding optical fiber performance, the G.652 fiber features attenuation levels of ≤0.36 dB/km at 1310 nm and ≤0.22 dB/km at 1550 nm. The G.655 fiber has slightly higher attenuation at ≤0.40 dB/km and ≤0.23 dB/km for the same wavelengths, respectively. Multimode fibers with core sizes of 50/125 μm and 62.5/125 μm exhibit attenuation values of ≤3.0 dB/km at 850 nm and ≤1.0 dB/km at 1300 nm. Their bandwidths vary, with the 50/125 μm fiber offering ≥500 MHz·km at 850 nm and ≥1000 MHz·km at 1300 nm, while the 62.5/125 μm fiber provides ≥200 MHz·km and ≥600 MHz·km at the same wavelengths. Numerical aperture values are 0.200±0.015 NA for the 50/125 μm fiber and 0.275±0.015 NA for the 62.5/125 μm fiber. The cut-off wavelength is ≤1260 nm for G.652 fibers and ≤1480 nm for G.655 fibers.
These characteristics make the GYFTA53 cable an excellent choice for applications requiring high mechanical performance, resistance to environmental conditions, and reliable optical transmission.
