Gyta53 Optical Cable Technical Parameters

Fiber optic splice closure knowledge brief Published 27 Oct 2021

Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

The GYTA53 is a single-mode, armored, outdoor optical fiber cable designed for direct burial and duct applications, featuring high mechanical strength, water-blocking, and environmental resistance.Cable Structure
  • Fiber Type: G.652D single-mode, 9/125 µm core/cladding diameter .
  • Fiber Count: Ranges from 2 to 288 fibers, with a maximum of 12 fibers per PBT loose tube .
  • Loose Tube: Jelly-filled, SZ-stranded around a central metallic strength member, typically steel wire of 1.6 mm diameter .
  • Filling Compound: Water-blocking gel fills the tube and core apertures to prevent moisture ingress .
  • Inner Sheath: Aluminum tape (0.2 mm thick) with polyethylene (PE) inner sheath (1.5 mm thick) for moisture barrier .
  • Armor: Corrugated steel tape (0.15 mm thick) provides rodent resistance and mechanical protection .
  • Outer Sheath: Medium-density polyethylene (PE), 2 mm thick, for impact and environmental protection .
Mechanical and Environmental Properties
  • Tensile Strength: Withstands over 1500 N .
  • Crush Resistance: 3000 N/10 cm .
  • Bending Radius: Minimum 20 times the cable diameter (20D) during installation .
  • Operating Temperature: -40°C to +60°C .
  • Cable Diameter: Approximately 14.5 mm .
Optical Performance
  • Attenuation: ~0.22 dB/km at 1550 nm wavelength .
  • Chromatic Dispersion: 18 ps/(nm·km), .
  • Zero Dispersion Wavelength: Around 1310 nm .
Applications
  • Installation: Suitable for direct burial, duct, aerial, and indoor floor installations .
  • Use Cases: Backbone networks, inter-city communication, high-speed data transmission up to 100 Gbps .
  • Protection Features: Water-blocking gel, armored steel tape, and double-jacket structure ensure durability in harsh environments and prevent rodent damage . The GYTA53 cable is engineered for high-capacity, long-distance optical networks, combining mechanical robustness with excellent optical performance, making it ideal for outdoor and direct-burial applications.
