An indoor/outdoor central loose tube cable with corrugated steel tape (CST) armour, for up to 24 fibres. The small diameter and light weight save duct space, and the armour resists rodents. Suits campus (inter-building) and building (intra-building) backbones.
Construction
- 2 to 24 fibres, 250 µm coloured
- Single gel-filled central loose tube
- Strength member: overall water-blocking fibreglass yarn
- Corrugated steel tape armour
- UV- and flame-resistant LSZH outer jacket
Why use it
- Gel-filled central tube protects the fibres
- Fibreglass yarn gives high tensile strength
- Steel tape armour resists rodents
- UV- and water-resistant
Typical uses
Inter-building and in-building backbones; duct, underground conduit and direct burial.
