Standard: IEC 60794; VDE 0888
CONSTRUCTION:
Optical fibers:
SM – single mode optical fibers (9/125 µm) G.657A1/A2 according to 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
Secondary protection of fibers: HFFR insulated „tight-buffered“, fiber of 900 µm diameter
Fibers designation: IEC 60304, TIA/EIA-598;
DIN VDE 0888
Cable core:
Cable core is without FRP, with one „tight buffered“ fiber 900 µm
Watertight element: Cable core is dry.
Peripheral supporting elements: Aramid fibers doped with swellable powder are used as water and mechanical protection.
Sheath ripcord: one or more ripcord placed under outer sheath.
Sheath: HFFR – Halogen free, flame retardante, yellow, orange, beige, tirquoise or gray colour (on customer request)
Flame retardant: IEC 60332-1
No flame propagation in vertical cable bundle:
IEC 60332-3
Halogen-free: IEC 60754-1
Non-corrosive combustion gases: IEC 60754-2
Low smoke density: IEC 61034-2
APPLICATION:
Easy strippable 900 µm diameter tigh buffer fiber.
Indoor applications, low smoke, zero halogen.
It is also used in power lines because of its non-metallic construction.
Indoor connection and patch cord applications.
