Aerial fiber optic cable is used very commonly in optical communication these days. We can see the
aerial cable hanging on the poles in your surroundings. As the aerial cable is exposed to a harsh outdoor
environment, the material used to make aerial cable must be sturdy and durable. Aerial cables are
available in a variety of designs to suit different types of overhead applications. This article can help you
learn more about aerial cables.
What is Aerial Fiber Optic Cable?
An aerial fiber optic cable is an insulated cable usually containing all fibers required for a
telecommunication line, which is suspended between utility poles or electricity pylons as it may
even be lashed to a wire rope messenger strand with a small gauge wire. The strand is tensioned
to satisfactorily withstand the weight of the cable for the span length, and it used on any climatic

hazard such as ice, snow, water, and wind. The objective is to keep the cable as low-stress as
possible while maintaining a drop in the messenger and cable to ensure safety. Generally
speaking, aerial cables are usually made of heavy jackets and strong metal or aramid-strength
members, and provide excellent mechanical and environmental performance, high tensile
strength, lightweight, easy to install, and low cost.
Aerial Cable Types
Based on the installation method, the aerial cable can be classified into two types: self-supporting
and catenary wire.
Self-Supporting Aerial Cable: Self-supporting aerial cable has cable bonded to insulated steel or
all-dielectric messenger for support. Examples of Self-supporting aerial cable types are
all-dielectric self-supporting (ADSS) and figure-8 cables.ADSS is an all-dielectric (without mental
elements inside the cable) self-supporting cable. It's usually used together with a power line or in
an area where lighting frequently occurs, while figure-8 its self-supporting messenger wire is
stranded steel wires, which is mental, and to some extent structure of the fig.8 cable, the central
strength member could be either steel wire or FRP. Non self-supporting aerial cable need to be
hanged under a messenger wire.

Catenary Wire Aerial Cable: Catenary wire aerial cable is common outdoor loose-tube cable that
can be lashed to a messenger or another cable (common in CATV).
Based on the structures and materials of the aerial cable, it can be divided into three main types:
GYTC8S, GYXTC8S, and GYXTC8Y.
GYTC8S: GYTC8S is a typical self-supporting outdoor fiber optic cable. It's suitable for aerial and
duct and buried applications. It provides excellent mechanical and environmental performance,
steel-wire strength member ensures tensile strength, corrugated steel tape, and the PE outer
sheath ensures crush resistance, water blocking system to improve the waterproof ability, small
cable diameter, and low dispersion and attenuation features.

GYXTC8Y : GYXTC8Y is a light self-supporting cable with the figure-8 shape in the cross-section
that is suitable for installation in the aerial environment for long-haul communications and duct
and buried applications. It provides high strength loose tube that is hydrolysis resistant, excellent
mechanical and environmental performances, small cable diameter, low dispersion and
attenuation, medium Density Polyethylene (PE) Jacket, and low friction installation features.
GYXTC8S: GYXTC8S is also suitable for installation in the aerial environment for long-haul

communications. It provides excellent mechanical and environmental performances, corrugated
steel tape and the PE outer sheath ensure crush resistance, water blocking system to improve the
waterproof ability, small cable diameter, and Low dispersion and attenuation features.
Applications Scenarios
The aerial cable is used to carry electronic signaling such as telephone communications, cable
service, and even as part of the electrical power distribution system within the local community. In
addition, aerial cables are used in outdoor aerial applications, long-haul and local area networks
(LAN), metropolitan area networks (MAN), subscriber network systems, junction communication
systems, CATV, and computer networks system.
Conclusion
Aerial cables can be laid using the original overhead open line poles, saving construction costs
and shortening the construction period. It is suitable for areas with flat terrain and small
undulations. Sun Telecom provides all aerial cable products and solutions to the global market.
