During the new optical route construction we provide trenching and HDPE subduct placement for optical cables, HDPE subduct pulling into existing underground facilities as well as self supported aerial optical cables and ducts.
Further we provide river and creek crossings and final asphalt surface arrangement.
When installation is completed, we obtain the acceptance documents from all landowners.
For the increasing demand of the number of fibers we offer an effective use of existing HDPE duct, already occupied by one optical cable. For such a network configuration, where an additional trenching and duct placement is very costly, we offer blowing of second optical cable into HDPE sub-duct already occupied by the existing one. For that process a Y shaped adapter is used. When installation is completed the subduct opening is closed by repair duct.
It is difficult to mathematically calculate the blowable distance of a second cable, however the field experience shows that distance is about 50% of common distance.
