Yes. JWZ posted a story about a repair in one such cable: https://www.jwz.org/blog/2002/11/engineering-pornography/ https://www.jwz.org/blog/2002/11/engineering-pornography/ And in this case, when the cable broke, it was hideously expensive to fix (downtime was costing $13,000/hour and this was back in 2002). EDIT: don't click directly on the link or you'll be horrified by what you see. Instead, copy the link. JWZ doesn't think highly of HN.
