To design and install effective applications, the bending radius and the lumen transmission loss (attenuation) of the cable should be considered. For recommended cable bending radius, see Technical Data table of the Fiber Optic Cables. Lumen transmission loss can result in an uneven appearance of light levels in the cable. An uneven appearance is minimized by illuminating both ends of the fiber optic cable. This is accomplished by looping cable in and out of a single illuminator or by using an illuminator on either end of a cable run. In general, using a 150 watt LyteLaunch illuminator, it is not advisable to install cable runs of more the 60 to 80 ft., depending on the ambient light levels of the installation area. In some applications that use very short lengths of cable, it may be acceptable to illuminate only one end of cable using a reflecting mirror end cap on the non illuminated end of the cable.

Depending on the illuminator and cable size being used, multiple cable runs can be achieved from each illuminator. See ClearFuse harness table for illuminator cable capacities.
