Product Name : Unitube Light-armored Cable - GYXTW
Fibers Count : 2-12 Fibers
Cable Diameter(mm) : 8.0
Weight(Kg/km) : 75
Maximum Tension(N) : 600/1500
Outdoor Optical fiber 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.
The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a waterresistant filling compound. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a polyethylene (PE) 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.
