Fiber Interface~ 85%Fiber Interface~ 85%
1) Optical “heart” is only ~15% of the total cost of a fiberoptic component
2) Fiber interface or “packaging” is ~85% of cost
3) Companies have focused on optical “heart” and traditional packaging

All current technology involves individual fiber alignment
Sub-micron alignment is neccessary in many cases
Many expensive piece parts required
Fiberoptic components cost hundreds of dollars each
