I have 2 sites with multishelf chassis NCS2006-SA per site. They use ver 11.0 and Services are protected by Y cable.
I created Y cable protection group and circuit for FC8G to test.
The problem is:
- In both of sites, TX-Client port of Active 10x10G card changes TX signal each 1-2s. It's -40db, -27db, -15db. .... flapping.
- So strange, when I remove cable of FC8G to Y cable. And check signal, I see TX- client port of active 10x10G card have good signal -3db and no flap.
Any idea for this case? Thank so much!
How far away are both sites located?
It is ~ 60km.
I just tested with 10GE and it's ok.
In my system, i have edfa-17 and dcu950 (Designed by ctp with 60km and 30db loss)
Please find the attached video about flapping signal.
