Me shopping for LC cables: Ooo, they come in pretty colors! I want the yellow ones...
The multi-mode transceivers in my shopping cart: No you don't. No. Stop. STOP
Joke explanation:
Multi-mode transceivers require multi-mode cables to function, which come in a handful of colors. Aqua and violet correspond to the OM3 and OM4 specs which are commonly in use today.
Single-mode transceivers require single-mode cables to function. Single-mode cables are always yellow, unless they're shielded for outdoor use, then they're black.
The two kinds of gear look very similar but are NOT compatible with each other and mixing them up will probably not work at all.
