Nexus 93180YC-EX and 93180LC-EX, cables supporting port capabilities

[kbyrd]

I am working on a data center design and need to understand the cables that I need to support the speeds supporting on the 93180YC-EX and 93180LC-EX

If I show the following from a YC:

sw-p10r-n9k-ag22-1# sho int eth1/49-54 capabilities | I Speed
  Speed:                 1000,10000,25000,40000,50000,100000
  Speed:                 1000,10000,25000,40000,50000,100000
  Speed:                 1000,10000,25000,40000,50000,100000
  Speed:                 1000,10000,25000,40000,50000,100000
  Speed:                 1000,10000,25000,40000,50000,100000
  Speed:                 1000,10000,25000,40000,50000,100000

Given the connector of this uplink port, how many interfaces and what is the interface for:

1gb, 10gb, and 25gb connections?

For example, I think I could use a QSFP-4SFP10G-CU1M and connect 4 SFP+ to a 40gb port. Does this cable also support 1g SFPs?

How is 25gb supported?

Sorry for these Layer 1 questions....I'm just not seeing it!

Here is the 93180-EX white paper:
