An all-dielectric stranded loose tube cable with two black polyethylene jackets and a fibreglass yarn strength layer between them, which also gives rodent protection. Designed for direct burial and lashed aerial installation.
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)
- Strength member: overall water-blocking fibreglass yarn
- Outer jacket: black UV- and water-resistant polyethylene (PE)
Why use it
- All-dielectric construction, up to 288 fibres
- Gel-filled loose tubes protect the fibres
- Fibreglass yarn gives high tensile strength
- Double jacket gives extra mechanical protection
- UV- and water-resistant
Typical uses
Inter-building voice and data backbones; duct, underground conduit and direct burial.
