Capacitor on USB cable?


I was messing around with a USB camera. I wanted to change the cable because is trimmed but as I was cutting it I saw a small thing (image below).

Its purpose is to prevent interference at high frequencies signals.


It may also work without it and with a cable as short as possible.
