Long haul fiber

Hello guys,

I've been in the L2-L3 business at my job primarily, and now I'm migrating towards learning the optical side of things. What I'm wondering about is what to they mean when they say the box has capacity X, and then the fiber itself has capaxity >X? Is it "switching" capacity versus propagation capacity?

For example, "the Infinera XT-S 3600 has 1.2-2.4T capacity with up to 25.6Tb in the extended C band". I'm a bit unsure if it is exactly the same as the L2-L3 capacity definitions.
