| Abstract: | This paper analyzes why the crosstalk is produced in optical node,and also analyzes the crosstalk of cascade system of OXC and OADM.The influence of both optical switch's insulation and the input signals power difference on system BER were calculated and analyzed.We also simulate it in cascade system of OXC and OADM,and draw the conclusion that non-ideal character of optical switch's insulation is the main reason for producing crosstalk and equalizing the optical power before the optical switch has better effects,etc. |
