On the topic of FEC modethought I'd share something I found a while back
when testing the ACX5448 with an MX960
The ACX5448 40 gig interface defaulted to FEC74... the MX960 40 gig interface
on an MPC7E-MRATE module default to FEC "NONE"
40 gig link would not come up

100GE standards either mandate FEC91 or do not mention it. But

Just upgraded to 19.4R1.10: same situation, FEC91 is needed to bring
100G links up.

There are some that worked on 18, and others only worked on 19.
Could be where we got them from. Didn't have the time to work it out -
1Gbps optics are the exception on

I'm using 1G optics on MX204 with 18.1. Not sure why you need to go to
19...

Thanks. I'll upgrade and
Hi Emmanuel,
We haven’t had a lot of „good experience“ with Junos 17.4 on MX204.
I would recommend to upgrade to latest s point release within the 18.1R3 train.
We had issues with certain D/CWDM internal mux optics like CLR4 or CLR4+ before
that.
1G speeds are also broken with pre 18.1.
Good
Hello,
By chance, have somebody on this list succeeded in connecting at 100G a
MX204 to a Dell S4100-ON series ?
I didn't succeed.
MX204 <-> MX204 is OK.
Dell S4100 <-> Dell S4100 is OK.
MX204 <-> Dell S4100 is not OK...
I'm using the same brand of (compatible) QSFP28 10G-SR4. They just
differ
