How do you check the fiber connections between switches?

Hello,
I have a problem.
I have 5 switches in the company that are connected to each other using fiber optics (model: J4858C).
Unfortunately, I can not disconnect these optical fibers, and I need to locate them
which switches are connected to each other and on which ports.
(eg - SW1 - port 27 <-> SW2 port 28).
How can you check it out soonest?
Are the commands? Or maybe some application?
Sorry for my English.

Regards

If you want to know which switch is behind what port, you can use de command: show lldp neighbor to see behind which port the switches are connected.
