GYFXTY-FG is a round, all-dielectric drop cable for fibre-to-the-subscriber builds. It suits self-supporting aerial drops as well as lashed and conduit installation. An overall glass yarn layer adds mechanical protection, and two embedded FRP rods add tensile strength.
Construction
- 2 to 24 fibres, 250 µm coloured
- Two embedded FRP (fibreglass-reinforced plastic) rods
- Strength member: glass yarn
- Black UV- and water-resistant polyethylene (PE) outer jacket
Why use it
- All-dielectric construction
- Gel-filled central tube protects the fibres
- Embedded FRP rods give high tensile strength
- Overall fibreglass yarn adds further tensile strength
- UV- and water-resistant
Typical uses
Inter-building voice and data links; aerial installation; FTTx and access networks.
