Used by electric utilities on transmission lines with the voltage of 35 kV and higher for creating optical communication lines and protecting the power lines from lightning strikes.
Applied for aerial installation on distribution and power transmission lines for building long distance optical communication systems.
Used for distributed fiber optic sensing in different applications.
Used for indoor and outdoor applications where fire resistance is a must. Remain functional under direct flame for at least 180 minutes.
Applied in ducts, conduits and trays with no risk of rodent attacks. Can also be lashed.
Designed for high reliability in harsh environments with potential mechanical impact. Applied in all ground types, swamps, and harsh rivers.
Designed for air blowing in ducts and microducts for building reliable underground communication networks.
Designed for underwater application with increased crush and tensile loads.

Used for cost-effective one-step aerial installation mostly in rural areas where the spans between poles are not long .
Applied in substations for control purposes.
Used to create communication lines between the common distribution box and a location inside the building (including vertical runs), between entrances or corridors in office buildings.
Applied for aerial installation on transmission towers, lightning poles, between buildings and structures for communication networks in rural areas.
A standard dielectric cable for installation in ducts with no risk of rodent attacks
Central strength member (FPR)
Dry loose tube
Maximum rated design tension up to 607 lb
Up to 288 fibers
InDuct is a standard underground fiber optic cable. It’s an all-dielectric and UV-resistant design. This cable typically consists of a stranded core with a central strength member (FRP), dry loose tubes with optical fibers (one or more layers — it depends on the fiber count which can be up to 288 fibers) and a single outer jacket. The stranded core is fixed by water-swellable yarns. Additionally, water-swellable tape can be added.
Very important note: this InDuct cable has no levels of rodent resistance.
— It can be pulled into underground ducts and sewer pipes
— It can be installed along bridges, tunnels and other structures
— It can be installed into indoor/outdoor cable conduits and trays
— It can also be lashed
InDuct is a great solution for an FTTH build. Check how this InDuct fiber optic cable can be deployed in FTTH system (explore Underground Backbone and Underground Distribution on a scheme).
