Enhanced traceability of cables is provided using illumination. An embodiment comprises introducing a chemiluminescent (alternatively, fluorescent) solution into a chamber coupled to at least a portion of an insulating jacket that surrounds a transmission medium, the chamber being initially hollow and, in at least a portion thereof, comprised of a substance through which light is viewable, such that upon introduction of the solution through a port, light emitted by the solution is viewable through at least a portion of the chamber. In another embodiment, a first and second compartment contain a first and second substance, respectively, and are physically separated. When an opening is caused in the physical separation, the substances are allowed to mix, the substances being chosen as providing a chemiluminescent reaction upon the mixing, such that light emitted by the chemiluminescent reaction is viewable.

A traceable fiber optic cable assembly with an illumination structure and tracing optical fibers for carrying light received from a light launch device is disclosed herein.
