摘要

A temperature independent 80-Gb/s 100-km transmission system is demonstrated with the use of spectral phase modulation-based tunable dispersion compensator (TDC).The principle of dispersion compensation based on spectral phase modulation as well as the relationship between spectral phase modulation function and group velocity dispersion (GVD) are theoretically studied.TDC based on spectral phase modulation is implemented.The performance of 80-Gb/s transmission system is experimentally evaluated.The nonlinear relationship between temperature and temperature-induced dispersion fluctuations is demonstrated through the asymmetric temperature-induced power penalty without dispersion compensation.With respect to the low temperature area,the temperature-induced dispersion fluctuations are smaller than those in the high temperature area.By using the proposed TDC,temperature independent 80-Gb/s transmission is successfully demonstrated under a temperature range of -20 - 60 ℃ with a power penalty of less than 0.8 dB.
