A conduit for housing an optical waveguide is described comprising a rectangular cross-sectional exterior configuration and a cylindrical or semi-cylindrical interior bore. Also described is a method of installing a fiber optic conduit system, including forming a bundle of said conduits arranged as a stack one conduit in width, and forming a trunk line and at least one branch line. Also disclosed is a node housing for an optical waveguide network and a junction protector for an optical waveguide network installation comprising a hollow structure configured to retain a plurality of waveguide conduits, said protector comprising a trunk portion having open ends to receive first and second waveguide conduits, and a branch portion having an open end to receive a third wave guide conduit.

1. A method of installing a conduit system for housing an optic fiber conduit system within a surface, the conduit system comprising a plurality of conduits, at least one of the conduits comprising a rectangular cross-sectional exterior configuration, the conduits comprising an axially-extending cylindrical or semi-cylindrical interior bore, the method comprising the steps of: coupling together the plurality of conduits in end to end relationship to form a conduit string by inserting a coupling member comprising a removable sleeve within the bores of adjacent ones of said conduits; wherein said sleeve expands the bores of the conduits radially outwardly when inserted therein;forming a trunk channel within said surface, said channel having a width and depth for fitting said conduit string therein; andinstalling said conduit string within said channel, and restoring the surface with a material. 2. The method of claim 1 comprising the further steps of forming at least one branch by forming a branching channel connecting with but leading away from the trunk channel, separating one or more individual conduits from the plurality of conduits and directing said one or more individual conduits into said branch channel. 3. The method of claim 2 wherein said surface comprises concrete, asphalt or other hard surface, said branch channel and said individual conduit comprise a stub, said surface is restored with a removable material, and said method comprises the further steps of extending said stub during a subsequent installation stage, said extending comprising the steps of removing the material at said branch channel to expose the stub of conduit, extending said channel within said surface, exposing the terminal end of said stub above the surface, and joining a length additional conduit to said stub, installing said extended conduit with the extended branch channel, and restoring the surface. 4. The method of claim 1, wherein said step of coupling further comprises forming an end segment in respective ones of said conduits having a cylindrical external configuration, providing a tubular cylindrical external sleeve, and fitting said external sleeve over the respective ones of said end segments in end to end relationship to join said conduits together. 5. The method of claim 4 wherein said end segment is formed within each of said conduits by removing a portion of said conduit with a rotary cutting tool, said tool comprising an exterior shell having at least one cutting blade thereon, a central rod for insertion into said bore, and an annular space between the rod and the shell wherein contacting an end of the conduit with said rotating tool forms said segment. 6. The method of claim 1 wherein the plurality of conduits is bundled together at an installation site. 7. The method of claim 2 comprising the further step of providing sequential, non-repeating distance and directional markers on each of said conduits extending the full length thereof, bundling the plurality of conduits together into a bundle wherein the starting numbers on respective ones of said conduits within the bundle of conduits all differ from each other, determining the numerical differences in value between the markers on said conduits, and thereby differentiating the respective ones of said conduits from each other throughout said installation. 8. The method of claim 1 wherein said at least one conduit is monolithic. 9. The method of claim 1 wherein said at least one conduit has a width of at most 15 mm. 10. The method of claim 1 wherein said at least one conduit has a ratio of diameter of the bore to exterior diameter of the conduit of about 14:25. 11. The method of claim 10 wherein said ratio is within range of plus or minus 5%, 10% or 20% of 14:25. 12. The method of claim 1 wherein said at least one conduit comprises HDPE plastic. 13. The method of claim 11 wherein said at least one conduit is square in cross-section. 14. The method of claim 1 comprising the further step of forming a bundle comprising multiple ones of said rectangular conduits arranged as a stack one conduit in width.
