Stranded Loose Tube Cable With Aluminum Polyethylene Laminate (LAP)
for outdoor use (GYTA)
Description:
The structure of GYTA cable is to insert 250 micron optical fibers
into the loose sleeve made of high modulus materials and fill the
loose sleeve with waterproof compounds. The core of the cable is a
metal reinforced core. For some optical cables with core numbers, a
layer of polyethylene (PE) should be extruded outside the metal
reinforced core. Loose sleeve (and filling rope) around the center
reinforcement core to form a compact and circular cable core, the
gap in the cable core is filled with water-blocking filler.
Polyethylene sheathed cables were extruded after plastic-coated
aluminium strip (APL) was vertically wrapped.
Model: GYTA Fiber type: SM-9/125um-G652D Outer jacket: PE sheath Color of jacket: Black Material : Aluminum Polyethylene Laminate Strength member: Phosphating steel wire Material of filling: Filling Compound |
Important notice:
Many domestic small factories use inferior or waste optical fibers
to imitate A-grade optical fibers, non-woven fabrics as
water-blocking tapes, waste electric-wires and rubber slippers
smashed as raw materials for the outer sheath of cable. Those
inferior cables will cause many problems such as short transmission
distance, low bandwidth, intermittent signal and easy-to-crack and
water seepage of the cable jacket, etc. For the recent years, there
are many cases that many overseas customers who bought such
inferior cables from China were frustrated to find that the cables
can not be used after constructing. It’s not workable to return
them to China as the Chinese government will levy high import
duties on optical fiber cables. The customers cannot claim for any
compensation and suffered huge losses.
Characteristics.
Good mechanical and temperature performance
· High strength looes tube that is hydrolysis resistant
· Special tube filling compound ensure a critical protection of
fiber
· Specially designed compact structure is good at preventing loose
tubes from shrinking
· PE sheath protects cable from ultraviolet radiation
· The following measures are taken to ensure the cable watertight:
. Steel wire used as the central strength member
. Loose tube filling compound
. 100% cable core filling
. APL moisture barrier
