A specialized light source located in a box called an Illuminator sits outside the pond. Up to sixteen separate fiber optic light cables are bundled together at one end into a common fitting and placed in front of the light source (fiber optic harness). Light shines into the end of the fiber optic cables, travels through the cables, and out the other end, illuminating whatever the designer wishes to light up. Fixtures attached to the end of the cables can be placed underwater, next to the water, in between rocks, or almost anywhere in or out of the pond.
