A data cable includes a plurality of illumination devices, an application module, and a lighting control module. The plurality of illumination devices are adapted to receive a control signal to change an illumination characteristic of the plurality of illumination devices, and the control signal is indicative of a signal characteristic for data to be transmitted over the data cable. The application module is adapted to analyze the data communicated over the data cable to determine the signal characteristic. The lighting control module is connected to the application module and adapted to light the plurality of illumination devices at the data cable based on the signal characteristic.
