Extension cord USB for arduino

Hi, I want to use extension cord: Delock Products 82689 Delock Cable USB 2.0 Extension, active 15 m (if is necessary I will use a external source for 9V, for arduino). I use Arduino+homemade controller for Christmass light(I use at 9600 baud rate). Is this extension cord ok for this project?

I would expect it to work fine.
