Product Description
Description:GYFTA74 non-metal reinforced member, loose sheathed layer twist filled type, polyethylene inner sheath, glass fiber yarn reinforced, polyethylene middle sheath, nylon outer sheath for communication outdoor optical cable.
The structure of the cable is to set the single-mode or multi-mode fiber into a loose sleeve made of high modulus plastic filled with a waterproof compound. The cable core center is a non-metallic strengthening part. For thousands of fiber cables with certain core numbers, the non-metallic central strengthening part is extruding a layer of polyethylene.
The loose bushing (and filling rope) is twisted around the central strengthening member to form a compact and round cable core. The inner gap of the cable core is filled with an external extrusion of hydro blocking compound and a polyethylene inner sheath.
After the glass fiber yarn is strengthened, the cable is extruded into a polyethylene sheath, and then the cable is extruded into a layer of anti-ant nylon sheath.Features:Excellent mechanical and environmental performance
Good waterproof performance
Gel-filled Loose tube protect the fiber well
Bite resistance performanceStandars:The products comply with relevant standards of YD/T,IEC and ITU.Technical SpecificationRemark:1.D is the diameter of the cable; 2.The above parameters are typical value; 3.The cable spec can be designed according to customer's requirement.Optical fiberFiber Specifications:G.652.D single mode fiber |
