In addition to the QSA, note that 40G LR optics are using CWDM. You can therefore get 1270, 1290, 1310 and 1330 out of the optic. Not the favorites channels, but if that's OK for you, configure it as a 4x10G on the Juniper side. -- Make it clear before you make it faster. - The Elements of Programming Style (Kernighan & Plauger) -----Original Message----- From: Adam Thompson <athompson@merlin.mb.ca> Sent: 14 mai 2021 13:30 GMT Subject: RE: Juniper hardware recommendation To: Bjørn Mork Cc: nanog@nanog.org
OK, enough people have pointed it out :-).
Clearly I was wrong about the MX 2K family, I missed the SFP+ MIC completely. That is good to know.
However, the MX 10k family still only shows as being compatible with two QSFP cards. And yes, you can get a QSFP-SFP+ breakout cable, but those don't let you use SFP+ CWDM/DWDM transceivers.
