Underwater - GJLJL Unitube (12 - 96 fibres)
Type GJLJL is a submarine fibre optic cable. Intended for offshore in river and lake installations.
StandardsInternational : IEC 60793; IEC 60794; ITU-T Rec. G.650; ITU-T Rec. G.652
GJLJL is intended for river, lake offshore or direct burial installation. The design can incorporate 12 to 96 fibres in a stainless steel tube. The individually coloured fibres are in groups of 12 fiber. This cable type is longitudinal water-blocked through the use of polymeric filling compound. GJLJL are double sheathed with halogen-free black polyethylene including one layers of galvanized steel wire.
