Description

Standard: IEC 60794; VDE 0888
CONSTRUCTION:
Optical fibers:
SM – single mode optical fibers (9/125 µm)
(G.652D, G.655, G.657A1/A2)
MM – multi mode optical fibers (50/125 or 62,5/125 µm)
ITU-T Recommendation
Material of fibers:
a) core – Silicon glass: (SiO2) doped with Germanium Dioxide (GeO2);
b) cladding: Silicon glass (SiO2)
c) primary protection: Dual layer of UV-cured acrylate resin

Secondary protection of fibers: Filled loose polymer tube of PBT elastomer, filled with thixotropic jelly mass, loose laid fibers within tube – SZ stranded
Tube material: Polyester PBT-Polybutylene Terephtalate
Fibers and tubes designation: IEC 60304, TIA/EIA-598; DIN VDE 0888
Cable core:
Central tube: cable core is without FRP and in one tube placed max. 24 optical fibers.
Cable core is dry.
Armouring, rodent protection and peripheral supporting element: Glass fiber tapes adapted against the rodent as well as against water penetration. Glass fiber tapes provide additional mechanical protection.
Sheath ripcord: one or more ripcord placed under outer sheath.
Sheath: HDPE – high density polyethylene, black colour
(UV protection)
APPLICATION:
These optical cables are use for outdoor application, water-resistant and resistant to UV-radiation. Glass fibers provide resistance to tensile strains, suitable for fixed laying in cable ducts, conduits or direct burial.
The permissible temperature range:
– during installation: from -30°C to +60°C
– during operation: from -30°C to +70°C
– during storage and transport: -40°C to +70°C
Min. permissible bending radius:
– Operation: 20D
– Fixed: 15 D (D – diameter of cable)
Tensile strength, max. (kN): On customer’s request
