A stranded loose tube outdoor cable with one layer of corrugated steel tape (CST) armour between two black polyethylene jackets, for demanding installations including direct burial. Fibre counts up to 288, with S-Z stranding.
Construction
- 2 to 288 fibres, 250 µm coloured
- Gel-filled loose tubes
- Central strength member: FRP (fibreglass-reinforced plastic)
- Inner jacket: black UV- and water-resistant polyethylene (PE)
- Armour: corrugated steel tape
- Outer jacket: black UV- and water-resistant polyethylene (PE)
Why use it
- Gel-filled loose tubes protect the fibres
- Double jacket and armour protect against rodents and mechanical damage
- UV- and water-resistant
Typical uses
Inter-building voice and data backbones; duct, underground conduit and direct burial.
