Light Weight Aerial Adss 24 Core G652d Fiber Optic Cable
Description
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 communications medium,
installed along existing overhead transmission lines and often sharing the same support structures as the electrical conductors.
Features
Using single-mode fibers and light wavelengths of either 1310 or 1550 nanometres, circuits up to 100 km long are possible without repeaters. A
single cable can carry as many as 144 fibers. Usually, ADSS was used in 48 and 96 cores.
H: Height of Pole or Tower, Namely the distance betweeen lowest horizontal.
h: Requirement minimum distance or ADSS cable to ground
f: Maximum vertical sag of ADSS Cable
L: Span
∑L: Total Length betweek 2 tension fittings
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.

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.
