An apparatus including a first ferrule, a second ferrule and a tracing fiber. The first ferrule may comprise a cap. The second ferrule may comprise the cap. The tracing fiber may be configured to propagate light from the first ferrule to the second ferrule. The first ferrule may enable the light to be directed into the tracing fiber when the cap is removed. The cap of the second ferrule may be configured to scatter the light to provide an omnidirectional emission of the light from the second ferrule. The tracing fiber may be bundled with one or more data carrying lines in a cable. Each of the data carrying lines may be configured to enable a communication of data. The tracing fiber may be configured to propagate the light without interrupting the communication of data.
