Reserved length for optical cable in jacking pipe
Corning Optical Communications field trials have confirmed that a single air-assisted device can install 1500 to 2100 meters (5000 to 7000 feet) of optical fiber cable under good conditions. Longer lengths can be achieved by cascading devices (i., providing mid-assist). nts of any drive with economics being a key factor. Pit sizes will vary according to the excavation methods employed, although these ructed to provide a reaction against which to jack. 250-300mm at the bottom is sufficient. In places where underground pipes, electric main etc. come in the way trenches deeper than one meter shall be dug as necessary and DWC pipes shall be placed to protect the. The sub-hole tube should expose about 15cm of the remaining length of the tube hole in the hand hole. The interface between the sub-pipe in the hand hole and the plastic textile network pipe is wrapped with PVC tape to prevent the infiltration of sand. For loose tube and ribbon cable, the bend radius is specified at 20 times the cable diameter during tension/installation conditions and 10 times during static conditions (check the data sheet).
