All-dielectric self-supporting optical cable（ADSS）_汕头高新区奥星光通信设备有限公司

All-dielectric self-supporting optical cable（ADSS）

The ADSS optical cable adopts a loose layer twisted structure, in which 250 µ m optical fibers are inserted into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. A loose tube (and filling rope) is twisted around a non-metallic central reinforcement core (FRP) to form a compact cable core, and the gaps in the cable core are filled with water-resistant grease. The cable core is extruded with a polyethylene (PE) inner sheath, then twisted with aramid for reinforcement, and finally extruded with a polyethylene (PE) outer sheath or an anti trace (AT) outer sheath.

Product Features

Can be installed without power supply
Adopting AT sheath, with superior resistance to electric traces
Lightweight and with a small cable diameter, it reduces the impact of ice and wind, as well as the load on towers and supports
Large span, with a maximum span exceeding 1000 meters
Has excellent tensile properties and temperature characteristics

Applicable: self-supporting overhead structure
