Abstract
A fiber bundle consists of first optical fibers and second optical fibers. At the distal end of the fiber bundle, the first and second optical fibers are bundled in a square close-packed array or a hexagonal close-packed array. The first and second optical fibers are separated from each other at the proximal end of the fiber bundle so that the first optical fibers are tied as a first branch bundle and that the second optical fibers are tied a second branch bundle.
