24-core fiber optic cable ADSS4*6 single mode

This specification covers design and performance standards for single-mode fiber (G652 D) all-dielectric self-supporting (ADSS) cable. In the following, the structural and mechanical structure of 24-core ADSS4*6 single-mode fiber optic cable is discussed. All properties are fully compliant with the latest revision of TCI specifications.

24-core fiber optic cable ADSS4*6 single mode

PBN ADSS-SM is an all-dielectric aerial fiber optic cable capable of being used in aerial optical networks constructed with single-mode fiber conforming to ITU/TIA G652D. This cable is resistant to ultraviolet rays due to the use of black high-density polyethylene (HDPE). This cable is suitable for use in central resistant era applications and can be used with 2 to 144 optical fiber cores.

Central resistance member

Fiber reinforced polymer (FRP) with a diameter of 2.5 μm is used as a central resistive element. Young’s modulus of FRP is 50,000 N/mm2 and water absorption is 0.1% maximum.

loose tube

Love tubes are made of polybutene terephthalate (PBT) with a minimum thickness of 0.4 mm. The fibers are spirally placed in the loose tube to have the ability to expand and contract the fibers. In order to prevent water penetration, loose tubes are filled with thixotropic gel.

Cable core

Loose tubes and their fillers (if any) are located on the central resistive element. Fillers are polyethylene rods that are used to round the cable core when needed. It has a water-swollen thread wound around the central resistive element for waterproofing purposes. At the end, a binder thread is spirally wrapped around them to keep the core flat.

Swollen bar

To make the cable waterproof, the core is wrapped in inflatable tape. Inflating tape is also composed of corrosion inhibitors.

outer jacket

Black HDPE (High Density Polyethylene) according to ASTM-1248 covers the entire cable as a 2 mm thick outer jacket.

Ripcord

Under the outer jacket, two Ripcords are placed to assist the operator in removing the jacket.
