Loose tube stranding fiber optic cable also Thunder-proof cable
Outdoor aerial optical fiber cable is a kind of transmissions cable
which is especially designed to be hung on the poles. Abiding by
the existing overhead principles, aerial optical cable is commonly
applied to WAN/LAN telecommunication. Different types can be
installed as either catenary or self-supporting.
Many domestic small factories used 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 duty
on optical fiber cables. The customers cannot claim for any
compensation and suffered huge losses.
The fibers, 250μm, are positioned in a loose tube made of a high
modulus plastic. The tubes are filled with a water-resistant
filling compound. A Fiber Reinforced Plastic (FRP) locates in the
center of core as a non-metallic strength member. The tubes (and
fillers) are stranded around the strength member into a compact and
circular core. After the cable core is filled with the filling
compound to protect it from water ingress, the cable is completed
with a PE sheath.
