We lay cables across the ocean, which is surely a rougher environment than the Moon. No current, no marine life, and no corrosion. The temperature extremes on the Moon shouldn't be all that difficult to handle. I can see laying fiber-optic cable using technology from derived wire-guided missiles: fire a missile containing 100+km cable, go to whereever it lands, splice the cable to a new missle, etc. Repeat 20 times.... -- "Fools are always at the bottom of David Pugh the food chain."
