Cable description:
Cable containing up to 72 optical fibres in water blocked loose tubes (Maximum 12 fibres per tube) and solid
polyethylene fillers laid-up around a glass reinforced plastic (GRP) central strength member, water blocked
interstices, taped*, polyethylene overall sheathed and integrally bonded nylon jacketed
