TECHNICAL DATA
DUCT DIELECTRIC FIBER OPTIC CABLES24(2x12), 48(4x12) SINGLE-MODE
Specification: The cables will be manufactured and tested according to customer’s specification as
well as to international specification IEC60794 -1 and ITU-T G652 / G655 recommendations. Our
technical data herebelow presented will also be valid.
Description of cable: Fiber Optic Cables, loose tube type. Each loose tube contains 12 single mode
ITU-T G.652 or G655 fibers and jelly-filling compound. Loose tubes and PE fillers are SZ stranded
around a dielectric central strength member (FRP: fiber reinforced plastic) to form the cable core.Swelling water-blocking yarns will be applied inside and over the cable core. The core is wrapped by
a swelling water-blocking tape and covered by the inner black polyethylene sheath. Two reinforcing
layers of glass yarns are applied over the inner sheath. Overall, a black polyethylene sheath will be
applied.
Packing: The cables will be delivered in wooden drums appropriate for fiber optic cables and
suitable for safe transport, storage and installation. The length of cable per drum will be 4000±200m.
