In this paper we study the nonlinear performance of super-symbol (SUP) transmission. We analyze the spectral dip, a unique feature of SUP, as a function of various system parameters and discuss how this dip and the associated nonlinear benefit would vary with different baud rates and shaping blocklengths. We then conduct simulations to verify our analysis, by which we confirm that the SUP performance can be optimized via a judicious choice on the baud rate and/or blocklength. Furthermore, a nonlinear noise study confirms that the nonlinear benefit of SUP mainly comes from its significant nonlinear phase noise (NLPN) reduction.
