Research on Reduced Cost Apical Solutions

Description :  

CenturyLink has evaluated the current deployment costs associated with the apical fiber optic construction solution and have determined that we need to research on reduced cost apical solutions. In the proposed study, the following three alternatives and other innovative ideas (if any) will be investigated in the next six weeks. The study includes literature research, innovative ideas, lab tests, small-scale field trials and report-writing.

  1. Alternative 1: Filler in Trench – Investigate ways to lower the material and installation costs. Therefore, as part of the apical testing beginning in February, we need to research the viability of adding aggregates/fillers such as Recycled Tire Rubber (RTR) and gravel as fillers to the polyuria and tack coat material to reduce the quantity amount of polyurea and tack coat within the milled trench.

  2. Alternative 2: Asphaltic Material in Trench – Investigate if the solution can be redesigned using asphaltic materials. Testing utilizing tack coat to cover the cable and asphaltic materials as an alternate material to the polyurea material will be performed.

  3. Alternative 3: Milling and repaving/patching (no trench) – Investigate if milling, installation of apical optic fiber and repaving/patching can be a viable alternative.
