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.
Typical application:
— 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).
