<div style="font-size:12pt">As for 10G DWDM optics, it's not a very efficient way to use your ports, but you could hypothetically use a QSFP+ to SFP+ adapter like this one if you truly needed to run some in your MX304 chassis:

<br>
Unless I'm missing a trick, the MX304 doesn't have an answer to installing DWDM, bidi, or other fancy optics in the SPF+ ports on the MX204. QSFP+ breakout to 4 x 10G is supported, but only 4 x vanilla 1310 optics - you'll need an external OEO solution if
you want fancy 10G options.<br>
<br>
It otherwise seems a nice box on paper, although substantially more expensive than the MX204.<br>
