- I thought I had just mentioned this in a recent post. Northern Telecom
- encountered the same problem when laying fibre optic cables underground
- using a "ditch witch". Their mechanical engineers came up with a sheath
- (I vaguely recall it has a helical structure) which takes up the tension
- and protects the cable from breaking. Anyone from NT on the net?
