The Esplanade Riel illustrated is located in Winnipeg, Manitoba, Canada. This bridge is intended for pedestrian use only and has a restaurant in its base. In the example below the cable paths are aligned with the bridge centerline, so that structurally it differs only in the transfer of stresses through the tower to the foundation.

Telecommunications cable use RHH or RHW type insulation materials as defined in NFPA 70®, "National Electrical Code®," for use in dry, damp, and wet locations. Products with dual RHH/RHW ratings can be used in all locations. The following cable location definitions are derived from the 2008 NEC. To maintain a continuing level of quality on the production of cable, suppliers typically administer a Quality Management System (QMS) consistent with the latest issue of standards documents ISO 9000 and TL 9000 or an equivalent alternate quality system satisfactory to the purchaser. Quality and reliability requirements are of two types: Product and Qualification. Testing
