Introduction of FRP fiber reinforced core

FRP fiber reinforced core is an important component of optical cable / cable, which is generally placed in the center of optical cable / cable. Its function is to support optical fiber unit or optical fiber bundle, improve the tensile strength of optical cable, etc. Traditional optical cables use metal reinforcements. FRP non-metallic stiffeners are increasingly used in various optical cables because of their advantages of light weight, high strength, corrosion resistance and long service life.

FRP fiber reinforced core (glass fiber) is a new type of high-performance engineering composite prepared by pultrusion process after mixing resin as matrix material and glass fiber as reinforcement material in proportion. FRP non-metallic optical cable reinforcement overcomes the defects of traditional metal optical cable reinforcement, and has excellent corrosion resistance, lightning resistance, electromagnetic field interference resistance, high tensile strength, light weight, environmental protection, energy saving and other significant advantages. It is widely used in all kinds of optical cables.

Application scenario

As a non-metallic reinforcement, FRP can be used for indoor optical cables, outdoor optical cables, ADSS power communication optical cables, FTTx optical cables, etc


There are two kinds of packaging: wooden cable tray and plastic cable tray. (as shown below)


Characteristic advantages of FRP fiber reinforced core

(1) High tensile strength, high modulus, low thermal conductivity, low elongation, low expansion, and wide temperature range;

(2) Non metallic materials are not sensitive to electric shock and are suitable for climatic environment areas such as thunder and rain;

(3) Chemical corrosion resistance. Compared with metal core, FRP reinforced core will not produce gas generated by the chemical reaction between metal and ointment, which will affect the optical fiber transmission index;

(4) Compared with metal core, FRP reinforced core has the characteristics of high tensile strength, light weight, excellent insulation performance and no electromagnetic interference;

(5) The optical cable with FRP reinforced core can be installed close to the power line and power device, and will not be disturbed by the induced current generated by the power line or power device;

(6) The surface is smooth, the size is stable, easy to process and lay, and has a wide range of applications.

(7) FRP reinforced core optical cable is bulletproof, tooth biting and ant proof.

(8) There is no joint, fracture, burr or crack in the extra long distance (50km)

Storage requirements and precautions of FRP fiber reinforced core

(1) Do not put the cable reel in a flat position and do not stack it high;

(2) The reinforcing core installed on the plate shall not be rolled for a long distance;

(3) Do not suffer from collision, extrusion and any mechanical damage;

(4) Prevent moisture and long-term exposure, and prohibit long-term rain;

(5) Storage and transportation temperature range: -40oC ~ +60 oC;
