- You may have missed a small point; David Lesher proposed a
- fiber optic thread inside a conduit. You have to make a splice
- in the fiber optics inside the pressurized conduit. If you
- have an inner conduit with a different pressure, and alarm on
- changes in the differential, you are even more secure.
