GJA is a waterproof pigtail cable built from simplex subunits (900 µm tight-buffered fibre with aramid yarn) stranded around a central FRP strength member. An aluminium–polyethylene laminate is wrapped around the core before the outer jacket.
Construction
- 1 to 12 fibres
- 900 µm tight-buffered fibre
- Strength member: Kevlar yarn
- Central strength member: FRP (fibreglass-reinforced plastic)
- UV- and flame-resistant LSZH outer jacket
Features
- Stranded non-metallic strength members give higher tensile strength
- Outer jacket is corrosion-, water- and UV-resistant
Typical uses
General-purpose indoor distribution; outdoor-to-indoor interconnection for fibre distribution equipment.
