I have a requirement to terminate the dark fiber directly on a switch port.
We are going to have 10G fiber connects two centers distance of 20 Km.

hm...
if you have two strands, then you can use 10GB XFP/X2/XENPAKs for single mode fiber with ER marking - up to 40 km or even ZR (80km)

And you own the fiber the entire 20Km? Of course you can terminate dark fiber without the devices mentioned, fiber from point A to point B is just like fiber from point A to point B in your facility. The difference is that we are talking long distances and the need to regenerate the signal if the distance
is too great. Th equestion is, is it really dark fiber that you own or is it a layer 1 path carved out of a provider infrastructure.

DWDM, and CWDM are used to run multiple wavelengths over a single fiber, they still need regeneration of the signal end to end if the distance is too great.
