Fiber Optic Cable Color Codes
In the center, orange cable means multimode fiber and the beige connector indicates 62.5/125 fiber. On the right, the yellow patchcord indicates singlemode fiber and the blue connector means it is a

Transmission distance is affected by chromatic dispersion because the core of single-mode fibers is much smaller than that of multimode fibers. And it is also the reason why single-mode

For single mode fiber with up to 12 strands, the standard exterior jacket color is yellow. This distinguishes it from multimode fiber, which has an orange jacket, or other cable varieties like CAT5
