We discuss the characterization of continuous variable, optical quantum teleportation in terms of the two-quadrature signal transfer and conditional variances between the input and output states. We derive criteria which clearly define the classical limits and highlight interesting operating points which are not obvious from a calculation of the fidelity of the teleportation alone.
