Questions:
++ Is it okay if Twinax cable used on 10G ports of ASR 1001-HX ?
++ Should we use only SFP+ transceivers in the list no matter there's not much technical difference ?

Hello @deprasan ,
you should use optics listed as compatible with your network device for production network, because it gives you a sort of insurance that you are following the recommended guidelines. If in the future an issue will arise on the link having used a not listed not ufficially supported transcveir would be considered a wrong choice made by you.
see the following thread
https://community.cisco.com/t5/switching/does-asr-1001-x-support-twinax-cables/m-p/2911089
So i would not use an "unsupported" module on your router.
Hope to help

I had this problem too. I was using 3M Passive "CU" cables to connect to Nexus 9504. Kept getting the same until I switched to Active Twinax (ACU) cables, which are a min. of 7m and so not ideal for short intra-cabinet runs, but nonetheless the links came up right away and I can see the cable/transceiver in Inventory. This may be that Active is "best" for 10G and Cisco is forcing, or it could be a bug or "miss" in programming, but regardless using an Active Twinax cable should resolve this.
