FRP Rod Strength Member for Fiber Optic Cables
FRP Rod Strength Member for Fiber Optic Cables
Strength member for fiber optic cables, usually located at the center of fiber optic cables, is one important component of fiber optic cables by supporting optic fiber bundle and enhancing cables tensile strength.
FRP Rod / FRP strength member is made by thermal pultrusion technique which combines complex resin as body material with glass fiber as reinforcement at a certain ratio. Without drawbacks of traditional metallic strength member, FRP rod features excellent anti-corrosion, electromagnetic interference free, high tensile strength, low weight, saving energy and environmentally friendly, which are now widely used in various optical fiber cables.
Application
Central strength member for fiber optical Outdoor Cables, Indoor Cables, ADSS Cables, FTTx Cables, etc.
FRP Rod Features
1) High tensile strength, high modulus, low heat conductivity, low stretch, low expansion, wide range of temperature settings.
2) Insensitive to electric shock, suitable for the area with frequent lightning and raining.
3) Free from chemical corrosion. Compared with metal wire, FRP rod eliminates harmful gas, which can negatively affect cables transmission quality, born chemically by metal and filling gel.
4) Compared with metal wire, FRP rod is of high strength, low weight, excellent insulation and immune to electromagnetic interference.
5) Optical fiber cables with FRP rod are available to be installed tight close to power wire and power units, perfectly insulated, free from induction current interference. The transmission efficiency can be improved accordingly.
6) Smooth surface, stable sizes, easy processing and installation contribute to wide range of FRP strength member application.
