Scaling <str<strong>on</strong>g>N<strong>on</strong>linearities</str<strong>on</strong>g><br />
• Since the power per channel for S 2 is lower, S 2 is<br />
less affected by the ”single-channel” n<strong>on</strong>linearities<br />
SBS <str<strong>on</strong>g>and</str<strong>on</strong>g> SRS<br />
• The power of neighboring channels is less for S 2<br />
<str<strong>on</strong>g>and</str<strong>on</strong>g> thereby S 2 is less affected by CPM<br />
• S 2 are less affected by FPM. S 1 has higher power<br />
<str<strong>on</strong>g>and</str<strong>on</strong>g> the mixing products generated by channels far<br />
away rapidly decreases, leading to the same<br />
number of ”relevant” mixing products for S 1 <str<strong>on</strong>g>and</str<strong>on</strong>g> S 2<br />
• Since S 1 <str<strong>on</strong>g>and</str<strong>on</strong>g> S 2 have the same total power <str<strong>on</strong>g>and</str<strong>on</strong>g><br />
b<str<strong>on</strong>g>and</str<strong>on</strong>g>width the SRS effect is the same for both<br />
systems<br />
