PRODUCT DESCRIPTION
TECHNICAL STANDARDS FOR OPTICAL CABLE
General Introduction
  • Recoin's metal and non-metal hanging optical cables use single-mode optical fibers, placed in moisture-proof oil-filled loose tubes, with moisture barriers, a protective sheath for non-metallic cables, and two protective sheaths for metallic cables, galvanized steel braided hanging wires. Fiber capacity from 2 to 144 optical fibers.
  • Recoin cables fully comply with international standards IEC, EIA, ASTM, national standards TCVN, industry standards TCN, or customer standards...

Detailed components of the cable
  • Optical Fiber
    • The optical fiber used is single mode G.652D, step-index. The outer layer of the optical fiber is color-coded according to TIA/EIA-598-A standard. The primary coating and the outer ink of the optical fiber use ultraviolet-resistant material (acrylate), minimizing the impact of the external environment and lasting over time. When splicing, the primary coating can be easily stripped using specialized equipment without chemicals, without affecting the fiber. Components of the optical fiber such as core, sheath, ink... are non-conductive. The standard parameters of the optical fiber are specified as above table. All optical fibers used in one cable are from a single optical fiber manufacturer. The color coding rule of the optical fibers in the same loose tube is specified as the table below:

  • Central Strength Member
    • Made from non-metallic FRP (Fiber Reinforce Plastic) material, circular, continuous, non-conductive, without any defects. May be coated with PE if necessary to create uniformity for the cable. This component helps the cable and optical fibers not to be overly stressed and ensures cable flexibility during manufacturing, transportation, installation, and usage.
  • Loose Tube
    • The loose tube is made from Polybutylene Terephthalate (PBT) material, non-conductive. The loose tubes in a cable are color-coded according to EIA/TIA-598 standard and are specified as the table below. This loose tube contains optical fibers inside and is filled with a specialized moisture-proof compound (filling compound). The optical fibers are free and move easily. The loose tube is continuously fabricated, with a smooth surface, no bubbles, no wrinkles, no impurities.
  • Filler Rod
    • The filler rods are made from high-density Polyethylene (HDPE), non-conductive, color-coded, ensuring the overall roundness for the cable structure. These filler rods are solid, without bubbles, no impurities, smooth surface.
  • Filling Compound
    • The jelly compound used to fill the loose tubes and the cable core is specialized for optical cables, maintaining its properties at temperatures from -30°C to +70°C. It is anti-fungus, anti-rodent, water-blocking, non-conductive.
  • Waterproof Component
    • This component includes moisture barriers, ensuring the cable is water-blocking. All materials are non-conductive.
  • Cable Strand
    • The optical cable core is stranded in a circular shape, providing the highest strength and flexibility.
  • Additional Reinforcement Component
    • For metallic cables, galvanized steel wire braid is used. For non-metallic cables, aramid yarn is used for additional reinforcement.
  • Corrugated Steel Tape
    • A protective layer of corrugated steel tape can be used to enhance cable protection, ensuring the cable is not overly stressed and can withstand external mechanical impacts.
  • Cable Sheath
    • The outer sheath is made from black high-density Polyethylene (HDPE), ensuring the cable's mechanical strength and protecting the internal components from external environmental impacts.
  • Hanging Wire
    • For metallic cables, galvanized steel wire is used for hanging. For non-metallic cables, aramid yarn is used. The hanging wire ensures the cable is securely fastened during installation.
