Abstract

　　The use of various types of sewer pipes is an attractive alternative for the installation of fiber optical cables in the complex infrastructure of cities. The new development uses robots to attach the cable to the sewer wall. Armored cable is required for these installation to provide mechanical strength during installation and rodent and chemical protection after installation. This paper will provide data on the incorporation of either coated steel or coated stainless steel in a bonded sheath configuration as a chemical barrier to moisture, acids, bases, fuels and hydrogen sulfide that may be present in the sewer environment.
