    FRP Fiber Optic Cable

TFcomposite‘s FRP fiber optic cable is a self supporting and bow type fiber drop cable with 2 parallel FRP strength member. FRP stands for fiberglass reinforced plastic material, it has the strength of steel wire but less weight, and the FRP is also corrosion resistant and durable. As result, this structure is ideal for fiber to the home drop cable.

Product performance introduction

FRP Fiber Optic Cable Features

Light Weight & Excellent Tensile Strength
Prevent Cable buckling
Most Suited for Multi-Loose Tube, Uni Tube, Slotted Core & Ribbon Cable Designs
Used as central or peripheral reinforcement in fibre optic cable
Dual Advantage : Reinforcement during installation as well as reduce stress on signal carrying optic fibre /conductor
Prevent sagging in aerial installation
Cost effective solution as a strength member


FRP Fiber Optic Cable


FRP Fiber Optic Cable Application


It is a di-electric composite cable strength member widely. It is designed to provide excellent tensile strength performance while maintaining high degree of stiffness, preventing cable buckling over its entire service life. It is most suited for loose tube, uni-tube, slotted core or ribbon cable, typically used as central or peripheral reinforcement in fiber optic cables. FRP Fiber Optic Cable serve a dual purpose. It provides cable reinforcement during installation, reduces tension on signal carrying optic fiber/ conductor. The lightweight FRP prevents the cable from sagging in aerial installations and its rigidity and strength takes on the load of cable.


Let’s compare FRP with Steel as a strength reinforcement in fiber optic cable:


Parameter FRP Composites Steel
Corrosion, rot and
and insect resistance
Resists a broad range of
chemicals and is unaffected by
moisture or immersion in water.
Resists insect damage. Painting
is only suggested when exposed to
UV rays/direct sunlight.
Subject to oxidation and
corrosion. Requires painting
or galvanizing for many
Strength Has greater flexural strength
and pound-for-pound
is often stronger than steel
and aluminum in the lengthwise
Homogeneous material
Weight Weighs 75% less than steel
and 30% less than aluminum
Could require lifting
equipment to move and place
Electrical conductivity Nonconductive
High dielectric capability
Conducts electricity
Grounding potential
Thermal properties Good insulator with low thermal
Conducts heat
Stiffness Will not permanently
deform under working load.
Modulus of elasticity:
2.8 x 106 psi
Modulus of elasticity:
29 x 106 psi
Impact resistance Will not permanently deform
under impact. Glass mat in
pultruded parts distributes impact
load to prevent surface damage,
even in subzero temperatures.
Can permanently deform
under impact
Color Color is molded within
No painting required
Must be painted for color,
may require repainting
over time
Cost Lower installation costs, less
maintenance and longer product
life allow for a lower lifecycle
Lower initial material cost
More expensive to maintain
Much higher over time

FRP Fiber Optic Cable


Fiber to the home drop cable

  • Stranding :
    the required number of elements (tubes or fillers)
  • Tube :
    thermoplastic material, containing up to 12 optical fibers and filled with a suitable water-tightness compound
  • Core Wrapping :
    water-blocking tape & yarns (dry core)


Q :

Where does FRP Strength Members fit into Fiber Optic Drop Cable?

A :

FRP reinforcement is not the messenger, but in a common configuration will straddle the optical cable within the jacket. In the case of Multicom fiber optic cable, we have constructed our cable in such a way that the optical fiber has the absolute least exposure and the FRP strength members are in a position to guard the hair-thin optical cables to keep them out of harm’s way.
