Experimental study on temperature dependence of dispersion of G.652 fiber and its effect on high speed optical communication system and compensation

Temperature dependence of dispersion of G.652 fiber is experimental studied. The dispersion and dispersion slop variations over a temperature rang of 80°C, from -20°C to 60°C are measured. The effects of temperature dependence of dispersion on 80Gbit/s 100km OTDM system is experimental studied. Eye diagrams ascribed to the temperature of -20°C, 0°C, 20°C, 40°C, 60°C are demonstrated after 100km transmission link. The effect was also evaluated by BER curves. At last, dispersion thermal coefficient and dispersion slope thermal coefficient of dispersion compensating fiber were experimentally measured. The possibility of dynamically compensating chromatic dispersion and chromatic dispersion slope of G.652 fiber due to environmental temperature alterations by controlling the temperature of dispersion compensating fiber is proposed.
