A low loss cable system adapted for use as a cable landfall system. The cable system comprises a cable having a plurality of cores. Each core comprises a conductor, a first insulating layer, a second electrically conductive layer and a third layer. The cable comprises two sections, connected at a connection point CP. A first section of the cable is arranged to be exposed to a landfall area and a second section of the cable is arranged to be exposed to a submarine area. The cable is arranged such that circulating currents are prevented or reduced in the second conductive layers of the cable in the section exposed to the landfall area, thus assisting in maintaining the ampacity of the cable in this section without, or by reducing, the need to increase the cross sectional area of the cable in the landfall area. This is accomplished by electrically connecting the second conductive layers of the cores to each other at the connection point. At a distal end of the first section of the cable, the second layers are arranged to leave an open ended termination, thus avoiding a closed circuit that would otherwise create circulating currents in the second layers of the first section, thus maintaining ampacity. 1.

The tape also includes an adhesive layer disposed on a second and third portion of the first major surface, the adhesive layer capable of adhering to a concrete or asphalt surface, such as a road, curb, or walkway. 1. A method of deploying a communications network , the method comprising:forming a trench in a road surface having a width and a bottom surface that is below surface level of the road;forming a channel in the bottom surface of the trench, the channel being narrower than the width of the trench;deploying a distribution cable into the channel; anddisposing a distribution cabling tape into the trench directly above the channel.2. The method of claim 1 , wherein the distribution cabling tape comprises a resilient polymeric base sheet having a first major surface and a second major surface claim 1 , and an adhesive layer disposed on the first major surface claim 1 , the adhesive layer capable of adhering to the road surface.3. The method of claim 2 , wherein the second major surface of the distribution cabling tape comprises a patterned surface having a plurality of raised structures.4. The method of claim 3 , wherein the second major surface of the distribution cabling tape comprises a coated surface.5. The method of claim 4 , wherein the coated surface comprises a surface coated with at least one of a thermoset claim 4 , a thermoplastic claim 4 , and retroreflective elements.6. The method of claim 1 , wherein the road surface comprises concrete or asphalt.7. The method of claim 1 , wherein the distribution cable comprises at least one optical fiber.8. The method of claim 1 , wherein the distribution cable is a pre-fabricated distribution cable assembly.9. The method of claim 1 , wherein the trench and the channel are formed using road ...

A conductor arrangement is for a collection of subterranean wells for recovering fluids from an underground structure. A frame is provided with several conductor guides, each forming an inlet opening for a conductor in an upper portion of the frame and an outlet opening for the conductor in a lower portion of the frame. The conductor is arranged to border a portion of a borehole towards a surrounding unconsolidated mass and has been passed through the conductor guide and down into the unconsolidated mass. The conductor guides are arranged in a mutually diverging manner in the direction from the inlet opening, and each conductor is extendable by a bend, the deflection angle of the bends providing mutually parallel center axes in coupling interfaces arranged in upper end portions of the bends. 1.
