A fiber optic delivery system and side pocket mandrel removal system. In one example, a system for making optical connections in a well includes an optical connector positioned in the well, and another optical connector displaceable into operative connection with the first optical connector after the first optical connector is positioned in the well. In another example, a method of making optical connections in a well includes the steps of: positioning a tubular string in the well; then installing an assembly in the tubular string, the assembly including an optical connector; and then displacing the optical connector into operative engagement with another optical connector in the tubular string.
