Elecom USB cable B USB2.0 (USB A male to USB B male) 3m USB2-FS3 with built-in ferrite core

Suitable for high speed transfer devices. You no longer need to shorten the cable to the last minute. We have completed a cable that strongly protects against foreign intruders.Ferrite cores are more effective the closer they are to the cable. Since the ferrite core is embedded in the sheath (cable covering), it is more effective than conventional ferrite cores. No need for ferrite cores anymore.A shield is essentially ineffective if it is not grounded. This product strongly prevents external noise due to the electromagnetic shielding effect of the ferrite sheath.Even if the ferrite sheath is embedded, the thinness and softness of the conventional cable will not change.
