GYFXTY 5.0mm Central Loose Tube Outdoor Cable for FTTH Access Network PE Sheath FRP Black
The optical fiber in the middle of central loose tube, the PBT tube are filled with a water-resistant filling compound. Outer the tube,there can add aramid yarn (kevlar) for strength member if customer request, and two parallel FRP strength member are placed at both two sides. The cable is completed with a polyethylene (PE) sheath. It is a good choice for aerial or duct application.
