摘要：
We offer a proof-of-concept experiment for reducing effects of second and third order intermodulation and second harmonic distortions in multi-carrier optical transmission. Experimental results with feed-forward optical compensation show little dependence on the amount of distortion terms, achieving 5 dB improvement in the EVM distortion floor level. The limiting trade-off between compensating for second and third harmonic distortions simultaneously was verified. Despite this outcome, the small difference between the observed linearized solutions with and without the presence of harmonic distortions indicates that the proposed solution may allow for maximal exploitation in a-RoF channel capacity.
