up to 24 fibres, Euroclass B2ca

metal-free, dry interstices, gel-free loose tube,
rodent protection, flame redardant, longitudinally watertight

1 ≤ 24 fibres
2 Loose tube
3 Glass armour
4 Ripcord
5 FR/LS0H sheath


Robust, non-metallic fibre optic outdoor and indoor cable with one central dry loose tube.
High crush resistance for high transmission reliability.
Easy to handle due to cable construction with dry interstices and gel-free loose tubes.
Longitudinal water-tightness by swelling yarn.
Non-metallic rodent protection.
The two coloured ripcords are easy to identify and enable the safe opening of the cable sheath.
Flame retardant halogen-free FR/LS0H sheath.
LAN backbone, access and riser zone.
Connection cable between the building distributors and/or floor distributors.
Suitable for laying in cable trays, ducts and vertical shafts.
Can also be spliced in all FO distributors and joints.
The cables are available with different types of optical fibre (see fibre data sheets).
