Light Weight Aerial Adss 24 Core G652d Fiber Optic Cable
ADSS Fiber Optic Cable is short for All-Dielectric Self-Supporting Fiber Cable. ADSS is a type of optical fiber cable that is strong enough to
support itself between structures without using conductive metal
elements. It is used by electrical utility companies as a
installed along existing overhead transmission lines and often
sharing the same support structures as the electrical conductors.
- ADSS is an alternative to OPGW and OPAC with lower installation
- Strong structure to allow lengths of up to 700 metres to be
installed between support towers.
- Light weight and small in diameter to reduce the load on tower
structures due to cable weight, wind, and ice.
- No strain, to maintain low optical loss throughout the life of the
- The cable is jacketed to prevent moisture from degrading the
- The jacket also protects the polymer strength elements from the
effect of solar ultraviolet light.
- The cable jacket and gel coating of fibres provides protection from
Using single-mode fibers and light wavelengths of either 1310 or
1550 nanometres, circuits up to 100 km long are possible without
single cable can carry as many as 144 fibers. Usually, ADSS was
used in 48 and 96 cores.

ADSS Construction details
ADSS Central Tube Structure Fiber Optic Cable Construction Image
the fiber of a certain length is placed in a PBT loose tube filled
with water-blocking material. Then it is wrapped with aramid yarn
according to the desired tensile strength and extruded with PE or
AT sheath. This structure has a smaller diameter and lighter
weight. But the fiber length is limited.
ADSS Strand Structure Fiber Optic Cable Construction Image
the fiber loose tubes are surrounding around a central strength
member (usually as FRP material). And the rest parts are similar to
the central tube structure. This type is able to obtain longer
fiber length. Although the diameter and weight is relatively big,
it is better to be deployed for large span applications.
- No metal wires are used in an ADSS cable with loose buffer tubes,
or arranged in a ribbon configuration
- Small plastic tubes each containing up to eight fibers are filled
with a gel compound, and stranded around plastic rods
- Wrapped with polyester tapes and encased in a pultruded glass
reinforced plastic tube
- Outer sheath is of protection the strength member from ultraviolet
light and from damage due to leakage current.
ADSS Cable Application
- ADSS cable is suspended in the electrical field due to the phase
- ADSS is good for the worst-case combinations of temperature, ice
load, and wind environments
- As a communications medium, installed along existing overhead
transmission lines and often sharing the same support structures as
the electrical conductors.
- Utilized for telecommunications by power utilities, telcos, and
private network groups
- Designed for installation on distribution and transmission lines
- Capable of being installed in close proximity to conductors if
security is a concern
- Suitable for underbuild applications, minimizing the need for
- Used for telecom networks where quick, low-cost installation is a
