Thanks for pointing out what confused me. :)
I think WL3e suggests it is a traditional OCI (client) and OCLD (line) pairing.
There is a single-slot OTR with a fixed LR4 client side and the line-side
optic in the same card, but that's relatively new.
I'd have a look at the PM stats on the Ciena to see if something isn't behaving
well. I recall we did have a problem with some Juniper/Ciena interop a couple
of years back which looked like intermittent circuit drops, but that proved to
be a Juniper problem rather than a Ciena one.
Cheers,
Rob
