I've not had much to do with Ciena or Infinera, but on gear I'm familiar with auto-negotiation performed between your gear and the local DWDM transponder and is a bit of a dark art. If it's at all an option, try and get the access interfaces swapper from copper to multimode and be done with it Cheers, Ben _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
