Use all-dielectric self-supporting (ADSS) cables, which are cost effective and convenient next-gen fiber cables that can be installed with simple-to-use hardware and can withstand very high-tension loads and long spans. Obviously, these fiber cables need to be resistant to electricity, which can be difficult as many aerial cables contain high tensile steel (HTS) for tensile strength. The existing 2" conduit contains 4x 1/0 XLPE cable (rated for direct-burial), so I plan on pulling outdoor rated, non-metallic fiber through the same conduit. My original plan was to trench new conduit and run CAT8, but given that the existing run is all "customer side" and installed by the former. Most aerial fiber optic cables are installed by lashing to a steel messenger wire strung between poles, but there is a category of cables with special high-strength jacket designs called all-dielectric self-supporting (ADSS) cables. ADSS cables are designed to withstand very high-tension loads. On large facilities, it is sometimes a good idea to provide separate duct bank systems, including manholes, for medium-voltage cables and keep them separated from the rest of the cables. As DPC sez, if the 15kV fries or explodes somewhere, are you going to take a big revenue hit with severed fiber?This composite cable combines the distance and bandwidth capabilities of singlemode fiber with the power-carrying capability of 14-AWG copper conductors. by Jeanna Deese and Chris Rivas Power over Ethernet—it may be an old concept, but new applications continue to be identified that are redefining.
