ADVA recently launched a QSFP+ transceiver with bidi support on each of its 4x10G breakout lanes: https://www.adva.com/en/newsroom/press-releases/20220308-adva-launches-new-bidi-pluggable-to-minimize-cost-and-latency-in-access-networks
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: https://www.flexoptix.net/en/transceiver/q-pct.html Best regards, Martijn ________________________________ From: NANOG <nanog-bounces+martijnschmidt=i3d....@nanog.org> on behalf of t...@pelican.org <t...@pelican.org> Sent: 14 June 2022 17:07 To: nanog@nanog.org <nanog@nanog.org> Subject: RE: Serious Juniper Hardware EoL Announcements > The MX204 is pure shocker!

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. It otherwise seems a nice box on paper, although substantially more expensive than the MX204. Cheers, Tim.
