Fiber patching between ODFs

I have a question that I hope some of you may know the answer to!

My company has a rather large building with two big sections. These sections are connected through a common technical room where fiber connection from both sections are patched to two different racks. In one of the sections, there are many stories as well.

The question is: is it possible to patch the fiber signal from one section to the other in this common technical room by just patching a SC to SC fiber cord between the racks? Or do you need some kind of switch to do the some sort of routing as well?

TL:DR: I want to just forward the fiber signal from one section to another in a big building through a common technical room.

Any help would be appreciated!
