Title:
SUBSURFACE FIBRE OPTIC CABLE NETWORK INSTALLATION
Document Type and Number:
WIPO Patent Application WO2002065182
Kind Code:
A3
Abstract:
A method of installing fibre optic cables consists of cutting a shallow and narrow trench or channel within a road surface or building wall. A narrow fibre optic cable is laid within the channel, and subsequently covered with a patch material. A branching cable network is provided by cutting at periodic and selected locations, a slightly broader and deeper region of the channel, within which cable loops and/or junction boxes are installed. The nodes may consist of branching nodes, or alternatively non-branching nodes containing a cable loop and/or junction box, the installation of which at a location permits a junction node to be formed at a close by location. The invention also consists of a junction box and cable winder for use with the system, as well as a method of installing fibre optic cables in soil using a slotted member to protect the cables in the trench.
