I have several nodes that have upsteam SNR that is a little low and we haven't found a solution to raising it, I'm open to suggestions.
1. The ingress has been cleaned up.
2. The nodes have been swept. Levels are as engineered.
3. The system uses DWDM, so U.S. light levels are a mute concern. They are within spec.
4. The nodes are on differant blades, ports and CMTS's.
5. All of the nodes are SA 6940 BDR Enhanced.
At the moment I can't think of any other info, I'm sure someone else will.
