Thanks for the info on this. I believe the high cost of fiber optics connections would be primarily due to the highly skilled labor and specialized equipment needed for hooking up fiber optics cables. I have observed technicians working on such projects at the US Geological Survey where I used to work. It appeared to me that these technicians have acquired many of the same skill levels as a micro-surgeon. I have also had the privilege to observe a micro-surgeon at work in an operating room when I was a medic in the Army. He let me look through a microscope so I could see what he was doing. Until I had seen this I would not have believed it was possible for one to have such a steady hand and to coordinate one's manipulations with such tiny surgical instruments with such fantastic skill.
