Experimental demonstration of improved equalization algorithm for IM/DD Fast OFDM
Experimental demonstration of improved equalization algorithm for IM/DD Fast OFDM
We experimentally investigate the fast orthogonal frequency division multiplexing (OFDM) scheme with improved performance in compensating asymmetric channel impulse response using single-tap equalizers. We demonstrate for the first time 18 Gb/s intensity modulation and direct detection optical fast OFDM over both 80 km standard single-mode fiber at 1.55 µm and 1.15 km hollow-core photonic bandgap fiber at 2 µm. The results show that the proposed algorithm has better performance and lower complexity than the previous schemes under asymmetric channel impulse responses. In addition, the results validate that the emerging 2 µm fiber-optic system can achieve the performance close to that of the 1.55 µm system.

Abstract
We experimentally investigate the fast orthogonal frequency division multiplexing (OFDM) scheme with improved performance in compensating asymmetric channel impulse response using single-tap equalizers. We demonstrate for the first time 18 Gb/s intensity modulation and direct detection optical fast OFDM over both 80 km standard single-mode fiber at 1.55 µm and 1.15 km hollow-core photonic bandgap fiber at 2 µm. The results show that the proposed algorithm has better performance and lower complexity than the previous schemes under asymmetric channel impulse responses. In addition, the results validate that the emerging 2 µm fiber-optic system can achieve the performance close to that of the 1.55 µm system.
