In optical cables, this can be caused by electromagnetic interference (EMI), which can introduce noise or disrupt the signal. After Google searching "Do Fibre Optic Cables attract any noise", most results return that they attract virtually no noise. Is this the case or are there some exceptions? Well, in the context of data communications, pretty much no noticable noise. This noise, known as amplified spontaneous emission. Optical cables, also known as TOSLINK or fiber optic cables, are becoming increasingly popular in audio systems due to their ability to transmit digital audio signals with excellent clarity.
