Metal
reinforced
component,
center
tube
type,
fully
filled,
steel-polyethylene
bonded
sheathed
communication
outdoor
optical
cable
The
structure
of
the
optical
cable
is
to
insert
single-mode
or
multi-mode
optical
fibers
into
a
loose
tube
made
of
high
modulus
plastic
filled
with
waterproof
compound
and
place
it
at
the
center
of
the
cable.
Water-blocking
materials
are
placed
between
the
outside
of
the
tube
and
the
steel
strip.
Two
parallel
steel
wires
are
embedded
in
the
sheath
as
reinforcing
supports,
and
the
outer
side
is
extruded
and
wrapped
with
polyethylene
bonded
sheath
to
form
the
cable.
Laying
methods:
non-self-supporting
overhead,
pipeline,
etc.
Application
scope:
suitable
for
long-distance
communication
and
inter-office
communication,
etc.
Execution
standard:
YD/T
769-2010
central
tubular
communication
outdoor
optical
cable.
Product
features:
-
Reasonable
design
and
precise
control
of
the
excess
length
of
the
optical
fiber
in
the
loose
tube
endow
the
optical
cable
with
excellent
mechanical
and
environmental
performance;
-
The
optical
cable
has
a
compact
structure.
Water-blocking
materials
are
added
between
the
steel
tape
and
the
loose
tube,
which
not
only
ensures
the
moisture-proof
and
water-blocking
effect
of
the
optical
cable,
but
also
guarantees
that
the
return
of
the
loose
tube
is
small
after
the
optical
cable
is
laid.
-
Optical
cables
are
light
in
weight
and
easy
to
lay.
-
The
optical
cable
has
excellent
flexibility
and
bending
resistance.
The
steel
tape
armoring
has
strong
pressure
resistance
and
certain
pressure
resistance
capacity.
