Stranded Loose Tube No-metallic Strength Member Armored Cable

What Is Stranded Loose Tube No-metallic Strength Member Double Armored Cable GYFTA53?

Stranded Loose Tube No-metallic Strength Member Armored Cable positioned between CO and first DP in FTTX network. Used as mainline cable which environment is in Buried ,Aerial, under earth Pipes, Poles etc.

• Stranded Loose Tube No-metallic Strength Member Armored Cable – GYFTA53
• Fibers Count : 2-144 Fibers
• Cable OD(mm) : 16.8-22.3
• Weight(Kg/km) : 255-415
• Tensile Strength Long Term/Short Term(N/1m) : 1000/3000

The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a waterresistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress.A layer of water-blocking material is applied around the cable core to prevent water ingress all the same. After a corrugated steel tape armor is applied, the cable is completed with a a PE outer sheath

ITU recommendation G.657 specifies two classes of single-mode bend insensitive fiber patch ca- bles: G.657 A and G.657 B. Each category (A and B) is then divided into two sub-categories: G.657.A1, G.657.A2 and G.657.B1, G.657.B2. The minimum bend radius of G.657.A1 fibers is 10 mm, of the G.657.A2 and G.657.B1 fibers is 7.5 mm and of the G.657.B2 fibers is 5 mm. Among, ITU-T G.657.A1 and ITU-T G.657.A2 fibers are fully compliant with ITU-T G.652.D fibers.
