This cable allows to play several if you bought the game with a single cable.
This is the same as the product sold with the game. The design is the same, ie a USB jack of a jack and a side of the other, all separated by taking "safety" which allows the cable to disconnect if you pull the USB plug and thus prevents any tearing.
Contrary to what is indicated, the cable is to be connected to a TV, but to a console (Xbox 360 or PS3) or to a PC hosting the Rocksmith game that is essential and must be acquired elsewhere.
Finally, identical in design to cable sold with the game, Ubisoft brand product is therefore of very good quality and is essential for multiplayer play the game Rocksmith.
