Standard Loose Tube No-armored Cable GYTA

Standard Loose Tube No-armored Cable - GYTA

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. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core,which is filled with the filling compound to protect it from water ingress.Then, the cable is completed with a PE sheath.

Optical fiber technical parameters-SMF:

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.
