<p>Hi Rick,<br>
<br>
Two weeks ago we did a short interop test with 400G ZR+ "bright"
transceivers (Cisco/Acacia DP04QSDD-HE0) between our Cisco
8201-32FH (XR 7.10.1) and an Arista DCS-7280CR3K-32D4-F (<span

4.30.2F)</span>, not sure if that included our whole optical
line system, but definitely across a FOADM to check if the signal
fits a the fixed filter. Worked fine and was uncomplicated.<br>
We do currently have a test setup in the lab with two Cisco
8201-32FH routers with one DP04QSDD-HE0 each sending alien waves
across our "normal" optical line system (ROADMs/amplifiers) and it
does work as expected.<br>
No services in production though yet.<br>
</p>
<p>One general thing that was maybe a bit surprising to us is that
it takes about 90s for the transceivers to link up after shut/no
shut or parameter change.<br>
</p>
Cheers,<br>
Chris<br>
