Aerial microduct is a UV-stabilised duct for installation on poles and messenger wire. It protects the fiber route above ground where trenching is not possible or not economical.

Key features

UV-stabilised HDPE compound for outdoor exposure.
Consistent stiffness for controlled sag between supports.
Compatible with standard aerial clamps and fittings.
Available in coils for long spans.

Applications

◈

Rural and intercity routeswhere trenching is difficult or expensive

◈

Future growthreserved paths for extra capacity, with no fibre cutting or splicing at height

Aerial solution

Aerial FTTH without trenching

An aerial FTTH route that needs no digging: the micro-duct bundle is installed on existing lighting or power poles in rural areas or wherever trenching is impractical. Compared with ADSS cable there is no fibre splicing in the air, and vacant pathways stay available for future expansion.

Cost effectiveReduce FTTH deployment cost by 20% versus ADSS
Time efficientReduce deployment duration by 30% versus ADSS
Future-proofInstall once and keep vacant pathways for future expansion
RobustProtects fibre cables against extreme weather
Installer-friendlySame architectures, components, cables, crews and tools as underground work
