Today's singlemode is quite abuseproof. Saying this, while having one cable in the office which was ridden over by carts, stepped, and stumbled on for years. I can't imagine UTP5/6, or especially 7 surviving this.
I'd say a purpose made, abuse proof optical cable is better than high frequency copper cabling.
