Cable Structure Details
  • 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 steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member.
  • Tubes (and fillers) are stranded around the strength member into a compact and circular cable core.
  • An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress.
  • The cable is completed with a PE sheath.
Frequently Asked Questions (FAQ)
What installation methods are suitable for this fiber optic cable?
This cable is designed for outdoor distribution and is highly suitable for pipeline laying, direct burial, and underground installation methods.
How is the cable protected against water penetration?
Watertightness is secured through multiple layers of protection: a loose tube filling compound, 100% cable core filling, and an Aluminum Polyethylene Laminate (APL) surrounding the core.
What types of optical fibers can be used in this cable?
The cable supports both Single Mode (SM G652D, G657A) and Multi Mode (MM 50/125, 62.5/125, OM3-300, OM4-550) fiber standards.
What is the function of the PE sheath on this outdoor cable?
The outer Polyethylene (PE) sheath provides critical protection against ultraviolet (UV) radiation and harsh weather conditions, ensuring long-term outdoor reliability.
What are the standard delivery reel lengths for this cable?
Standard cable reel lengths are available in configurations of 1km, 2km, 3km, and 5km.
How are the individual fibers identified within the loose tubes?
Fibers are color-coded in a standardized 12-color sequence (Blue, Orange, Green, Brown, Grey, White, Red, Black, Yellow, Violet, Pink, Aqua) for quick and accurate identification during installation.
