So me DSL pro viders are also using a hybrid f iber-co pper system, but as with cable’s co pper hybrids, this is expensive to build. The superspeedy DSL implementatio ns that are po pular in Euro pe and Asia wo rk because f o reign cities are densely po pulated and so many high-value custo mers can be accessed o ver sho rt distances. In So uth Ko rea, f o r example, half the po pulatio n lives in apartments, and mo st o f tho se custo mers live in and aro und Seo ul. This density also impacts co sts—since so many peo ple live in apartments, f o reign carriers run f ewer lines to reach custo mers, digging up less gro und o r stringing wires acro ss f ewer telepho ne po les. Their U.S. co unterparts by co ntrast need to reach a custo mer base sprawled acro ss the suburbs, so U.S. f irms have much higher inf rastructure co sts. S.
