The Samsung VG-SOCR15 is a 15 meter long Invisible Cable. This is useful when the 5 meter long cable that comes standard with your QLED TV is not long enough. With this you place your devices even further out of sight. You connect the Invisible Cable to the TV and the One Connect Box. Note: this cable is only suitable for the Samsung 4K QLED TVs. For the 8K QLED TVs you use the Samsung VG-SOCR85.
