Without any manhole, long durability, safely closed for fibre optic networks.
Function 1: Apertures of existing duct systems for branching off standard cables or internal speedpipe are closed safely and simply.
Function 2: For branches from the duct system no manhole is necessary any more. Install the branches wherever you want to minimize or optimize your routes.
Function 3: Due to the mechanical protection of the branch point you receive optimum results at blowing in fibre optic cables into the internal speedpipe even after decades.
