### AI overview

This article explains how fiber-optic patch-cable jacket colors commonly indicate fiber types, supported wavelengths, or connector styles. It describes yellow single-mode fiber, orange OM1 and OM2 multimode fiber, and aqua OM3 and OM4 multimode fiber, while noting that color improves identification and troubleshooting but does not affect light transmission.

### Source excerpt
