Underground STA armoured fibre optic cables
Loose tube optical fibre cables from 24 to 144 fibres with STA armour and PE sheath. This armour gives a protection against rodent and a higher mechanical resistance to crushing For installation in ducts by pulling or blowing with maximum tensile strengths of 150 Kp. These cables are designed for medium or long distance telecommunications networks with single mode fibre optic type ITU-T G 652D (EN 60793-2 – Class B 50 B 1.3). They can also be made with other types of fibres on request.
