ASU80 Self-Supporting Single Losse Tube Fiber Optic Cable
Non-Armored Uni-Tube optical cable with fibers placed in loose
buffer tube.The cable core is protected with jelly to prevent water
intrusion and migration, and coverwith a black polyethylene out
jacket. Two embedded FRP or metallic wire provide desire tension.
Feature
Small Size and Ligth Weight
Two FRP as strength member to provide good tensile performance
Gel Filled or gel free , good waterproof performance
Low price ,high fiber capacity
applicable for short span aerial and duct installation

What does the acronym ASU stand for?
When you find this abbreviation in the nomenclature of an optical
cable, it means that it is a self-supporting (AS) cable with a
single loose tube (U) through which all the optical fibers pass.
The number that accompanies the acronym refers to the number of
meters in which that cable model can support itself, that is, in
spans of up to 80m, spans of 100m or spans of 120. This span is
nothing more than the distance between the posts you will install
the support system for the cable.
ASU 80
The ASU80 optical cables are self-supporting in spans of up to 80
meters, therefore, they are indicated for cable passage in urban
centers, as within cities the poles are usually, on average, 40
meters apart, which guarantees a good support for this cable.
ASU 100
ASU100 optical cables are self-supporting in spans of up to
100meters, therefore, they are indicated for cable routing in rural
areas, where the poles are usually between 90 and 100 meters apart.
ASU 120
ASU120 optical cables are self-supporting in spans of up to 120
meters, therefore, they are indicated for the passage of cables in
environments where the poles are far apart, such as on roads and
crossings over rivers and bridges.
We still have self-supporting cables for longer distances on the
market, such as the ASU500, but the 80, 100 and 120 are the most
commonly used due to their applicability.
