The Gain of Performance of Optical WDM Networks

Table 2

Overview of the gain of performance.

Gain of	Expression	Equal parameters	Different parameters
Performance	$G={{\rho }_{N1}/{\rho }_{N2}|}_{P_b,H}$	—	$F_{N1}\ne F_{N2}$, $W_{N1}\ne W_{N2}$,
			$k_{N1}\ne k_{N2}$
Wavelength conversion	$G_k={{\rho }_{N1}/{\rho }_{N2}|}_{P_b,H,F,W}$	$F_{N1}=F_{N2}=F$,	$k_1\ne k_2$
		$W_{N1}=W_{N2}=W$
Using multiple fibers	$G_F={{\rho }_{N1}/{\rho }_{N2}|}_{P_b,H,W,k}$	$W_{N1}=W_{N2}=W$,	$F_{N1}\ne F_{N2}$
		$k_{N1}=k_{N2}=k$
Using multiple wavelengths	$G_W={{\rho }_{N1}/{\rho }_{N2}|}_{P_b,H,F,k}$	$F_{N1}=F_{N2}=F$,	$W_{N1}\ne W_N$
		$k_{N1}=k_{N2}=k$
