Cisco ONS 15454 - 100G licensing

​

Hello community,

After I tried to understand the datasheet, I'm having trouble understanding Cisco's 100G licensing on the LC for ONS 15454.

Can someone bring some clarity over this?

I would like to understand the difference between:

- 15454-M-100G-LC-C

- 15454-M-100GC-LIC

- 15454-M-LIC-100G

My main question is this 15454-M-100G-LC-C fully fonctionnal or do I need to purchase extra license on top?

Thank in advance,
