A central loose tube outdoor cable with steel wire armour between two black polyethylene jackets. The gel-filled tube stops water getting in and travelling along the cable; the double jacket and armour protect against rodents.
Construction
- 2 to 24 fibres, 250 µm coloured
- Single gel-filled central loose tube
- Inner jacket: black UV- and water-resistant polyethylene (PE)
- Steel wire armour
- Outer jacket: black UV- and water-resistant polyethylene (PE)
Why use it
- Double jacket and armour protect against rodents
- Gel-filled central tube protects the fibres
- Steel wire armour gives high tensile strength and crush resistance
- Compact, easy to install
- UV- and water-resistant
Typical uses
Inter-building voice and data links; duct, underground conduit and direct burial; FTTx.
