This product extends USB 2.0 signal between transmitter and receiver over twisted pair CATx cable. It supports USB 2.0 signals up to 50m and does not require any power. It can be used as a direct link or through a patch panel, provided the maximum length of 50m is observed, not for use through a switch. The transmitter and receiver have short fly leads on each end, the receiver being female USB, so if being used as a link for projector or printer, a short male to male lead will be required for the final connection.
