Why a cable beneath the Channel may still count as land cable

An argument over cables running through the Channel Tunnel turns on the difference between geography and engineering classification. The cable is physically beneath the seabed, yet it is installed like land cable inside a dry tunnel rather than laid in water or on the seabed. Calling it an undersea cable is geographically accurate, while calling it a submarine cable may be technically wrong. The exchange shows how infrastructure categories can diverge from ordinary descriptions of where the equipment sits.
