enter image description hereWhat kind of fiber connection does the top switch use? I know the bottom switch uses a multi-mode MTRJ connector but I want to connect the bottom switch to the top switch. This is practice for the CCNA exam. I am new to fiber cable connections :)

Thank you!

  • So is the top connector an LC or an SC?? They both look so similar I can't tell.

  • It looks like the same size on the video as nothing is to scale.

From Cisco's Datasheet:

100BaseFX ports: SC connector, 50/125- and 62.5/125-micron multimode fiber-optic cabling (only on Catalyst 2924C and 2-port and 4-port 100BaseFX modules)
