The 4FO (2x2) Duct + ADSS Loose Tube Fiber Optic Cable SM G.652.D Dielectric Unarmoured from Cablescom is a Universal Fiber Optic Cables with 4FO and Dielectric Unarmoured construction . Aerial self support figure 8 fiber optical cable configuration is the one in which the conductors and the steel strand which supports the cable are integrally jacketed. The cable portion is attached integrally with stranded steel messenger wires. Suitable for Aerial installation except on power lines. The cable design provides easy and economical one step installation and stable performance over a wide temperature range and is compatible with any telecommunication grade optical fibre. The strength member is designed to withstand the tensile forces of the installation and may be metallic or non-metallic. The design configurations of this cable consist of central tube or stranded loose tube.
The 4FO (2x2) Duct + ADSS Loose Tube Fiber Optic Cable SM G.652.D Dielectric Unarmoured from Cablescom is an ADSS - Aerial cable with 4 fibers within 2 loose tubes. This distribution cable for optical networks has a loose tube structure with PBT tubes filled with a thixotropic filling compound, a PKP polyethylene sheath and a fibre-glass reinforced plastic central element allowing it to be totally dielectric. It has swellable yarns and tapes to avoid water penetration inside the cable and mechanical reinforcements of aramid yarns as traction resistant. The optical fibers comply with ITU-T recommendations G.652D.
For outdoor use; Installation in outside plant underground conduits both as overhead lines.
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:
While using a loose tube construction in cables, you can:
The loose tube construction solution can be chosen for the following applications:
Dielectric unarmoured is a type of fiber optic cable protection that provides electrical isolation without the added mechanical protection of an armor layer. This type of protection is achieved by using dielectric materials such as aramid yarns or glass fibers to provide strength to the cable. Dielectric unarmoured FOC is typically used in indoor installations, where the cable is not exposed to the same level of mechanical stress and environmental factors as outdoor installations. It is also used in applications where weight and flexibility are a concern, such as in aerospace or automotive industries.
Single mode fiber uses a LASER light source, is a type of optical fiber with a small core diameter that allows only one mode of light to propagate. It is used in telecommunications and data transmission systems to transmit signals over long distances with low attenuation and high bandwidth. Single mode fiber is ideal for high-speed and long-distance applications, such as internet backbone networks, cable television networks, and fiber-to-the-home (FTTH) services. Its narrow core reduces the dispersion of light, allowing signals to travel further and faster than with multimode fiber.
