The cable core is water blocked using a combination of swellable tape and gel filling inside the tubes. All cables can be installed where there is a risk of having water filled ducts.

The cables come with 2, 4, 6, 8, 12 or 24 fibres in a gel filled unitube. The cable has glass yarn strength members.The armouring consists of 0.15mm corrugated steel tape. The fibres are colour coded for fast installation.
