The 2~24 Fibers ASU Cable(AS80 and AS120) is a Self-Supported Optical Cable, It was developed to provide the connection between devices, being indicated for installation in urban and rural networks, in spans of 80m or 120m. Because it is self-supported and totally dielectric, it has FRP strength member as a traction element, thus avoiding electrical discharges in the networks. It is easy to handle and install, eliminating the need to use strings or grounding.
It is mainly used in the communication route of overhead high voltage transmission system, and can also be used in the communication line under the environment such as lightning zone and long distance overhead line.
Structure Design
Main Features:
High strength non-metal strength member
Shorter span: 80m, 100m, 120m

Easy operation
ASU Cable VS ASU Cable
Compared with the stranded ADSS fiber optic cable, This fiber optic cable can not only save the use of imported aramid yarn, but also reduce the manufacturing cost due to the reduction of the overall structure size. Compared with the common 150-meter span ADSS-24 fiber optic cable , the price of the This cable of the same specification can be reduced by 20% or more.
