Inter­chan­nel Non­lin­ear­i­ties in Polarization-Multiplexed Transmission

35th Euro­pean Con­fer­ence on Opti­cal Com­mu­ni­ca­tion 2009

Abstract: We exam­ine the impact of cross-polarization mod­u­la­tion and cross-phase mod­u­la­tion in polarization-multiplexed sys­tems by means of com­puter sim­u­la­tions and show how symbol-interleaving reduces the XPolM-related penalty.

Notes: The fig­ures in the pre­sen­ta­tion slides dif­fer slightly from those in the paper, because in the paper we per­formed the sim­u­la­tions with a CW (PolDM) sub­chan­nel as probe while for the pre­sen­ta­tion we repeated the sim­u­la­tions with two QPSK-modulated sub­chan­nels. The non­lin­ear thresh­olds may seem quite high for NRZ DWDM inter­fer­ers, com­pared to other pub­li­ca­tions, but we used a com­par­a­tively large value of resid­ual dis­per­sion per span (256 ps/nm/km, cor­re­spond­ing to 16 km uncom­pen­sated SSMF) which effec­tively sup­presses inter­chan­nel dis­tor­tions from NRZ neighbors.
