This paper outlines an experimental investigation of an over-gigabit indoor visible light transmission system employing a quasi-phase-matching (QPM) device. To evaluate the effect of collecting lenses with different diameters, we measured the relationship between received optical power and bit error rate by using collecting lenses with diameters of 5, 8, 10, and 15mm. The experimental results confirmed that the relationship between the received optical power and the receiving area of the collecting lens was consistent with the analytical solution. We confirmed that a larger collecting lens is effective against the degradation caused by increased transmission distance, even if the optical output power of the wavelength converter is constant.
