STRENGTH MEMBER FOR OPTICAL FIBER CABLE FEATURES OF
NON-METALLIC FRP STRENGTH MEMBER FOR FIBER OPTIC
CABLE
|
| DESCRIPTION: |
|
It is manufactured
using E-glass fiber with heat resistant thermal
resin system. It is available in various coatings
including EAA, Tuff, Mega Bond and HDPE, which
allows easy handling, Tuff coating provides very
smooth surface, whereas Mega bond is suitable for
where high adhesion to up jacketing is desired.
|
APPLICATIONS |
|
It
is a di-electric composite cable strength
member widely known as FRP/ GRP rod. 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 rods 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. FRP combines the properties of high
performance glass fibers and polymer resin
to give a cost effective and superior
strength member for cables. FRP strength
members are also widely used in various
copper cables for last mile connectivity as
well as power transmission.

TYPICAL PROPERTIES
|
|
FRP is a light weight and has high tensile
strength Insensitive to the lightning strike,
suitable for the area with frequent lightning
and rain Free from the induction interference,
can be laid and installed close to the power
line and device
No harmful gas, which will affect the
transmission of the optical fiber, will be given
off from the corrosive metal.
