Can't get SFP links up on NV1544

I have two Netvanta 1544 (2nd Gen) Switches. I am attempting to connect them together using all 4 SFP ports for stacking. I have enabled the interfaces and checked all my connections but they are continuously down. I have not been able to get them to link up at all. I am on FW R13.2.3 and both switches were setup from the default config file from the Adtran site. SFP Diagnostic information pasted below. Thanks in advance!

Re: Can't get SFP links up on NV1544

For anyone who runs into this issue in the future. It was the JDSU transceivers that were incompatible. I replaced them with Finisar FTLF8524P2BNV transceivers and have my full 2500 Mbps on all 4 links over 1m aqua cables. I have pasted my new SFP diagnostic info below as well. Thanks!
