Product Details

Corning glass-yarn armored loose tube cables are designed for outdoor use for campus, city and intercity backbones in duct installations.






Product Description

The 72FO (6X12) Duct Loose tube Fiber Optic Cable OS2 G.652.D HDPE Dielectric Armoured Black (Part number: 072EPG-T3122P20) from Corning with 72FO and Dielectric Armoured construction. Conduit cables are underground cables, that may be conducted by duct or buried directly into the ground. There are several types of protections for this cable such as anti-rodent or double protection. Conduit cables are built to withstand harsh environments and are typically routed by pull or blow.

The loose -tube cable construction, by isolating the fibres from installations and environmental rigors, provides stable and highly reliable transmission parameters. The 2.0 mm buffer tubes and fibers in each tube are color -coded for quick and easy identification. The SZ -stranded construction further reduces installation and environmental influences on the transmission parameters and allows mid -span access. These slim and lightweight cables are designed with a1.1mm HDPE outher jacket for easy installation in conduits and ducts.

Fiber Type (ITU) - OS2 G.652.D

Each type of single-mode fiber has its own area of application, and the evolution of these optical fiber specifications reflects the evolution of transmission system technology from the earliest installation of single-mode optical fiber to the present day. Choose the right fiber is very important for each project/installation. The specification of the OS2 fiber is generally considered as the SMF standard for the single-mode fiber. For the OS2 G.652 fiber there are 4 subcategories: G.652.A, G.652.B, G.652.C, G.652.D.

The OS2 G.652.D single-mode fibers are the most used type of fiber for networking and communications applications. The OS2 G.652.D fiber type provides a zero dispersion at 1310nm wavelength therefor it is optimized for operation in the 1310nm Wavelength. The regular performance remains on the 1550nm wavelength.

Benefits of using the OS2 G.652.D fibers:

  • Backward compatibility with earlier versions;
  • Lower system cost;
  • Offers zero water peak and seamless splicing;
  • Lower splicing losses;
  • Supports longer cable runs.

FOC Construction - Loose tube

While using a loose tube construction in cables, you can:

  • Pull and stretch without causing fractures from bending or tension;
  • Have full resistant protection of the fiber core, cladding and coating (mechanical protection and UV protection);
  • Reach optimized performances at extreme temperatures;
  • Avoid the risk of environmental damage (including water damage).

The loose tube construction solution can be chosen for the following applications:

  • Direct buried;
  • Aerial;
  • Duct;
  • Rodent resistant;
  • Indoor and outdoor;
  • Water-blocking;
  • Temperature endurance.

FOC Protection - Dielectric Armoured

Dielectric Armoured is a type of fiber optic cable protection designed to provide a high degree of mechanical protection while maintaining electrical isolation. This protection is achieved by using an armor layer made of dielectric materials such as Kevlar, which is non-conductive and non-magnetic. This armor layer protects the cable from damage caused by crushing, impacts, and bending, while also providing protection from environmental factors such as moisture and temperature changes. Dielectric armored FOC is commonly used in indoor and outdoor installations where the cable may be exposed to harsh conditions.

Jacket Material - HDPE

HDPE (high-density polyethylene) is a jacket material that offers excellent protection against moisture, chemicals, and abrasion. It is highly resistant to impact, making it ideal for rugged applications where cables are exposed to rough handling. HDPE is also UV-resistant, and it can withstand extreme temperatures, making it a good choice for outdoor and industrial environments. However, it is less flexible than other materials, which may make it difficult to use in certain applications.
