What does a yellow fiber optic cable mean? The outer jacket color indicates the fiber's internal mode. A Yellow jacket universally signifies Single-mode fiber (OS1 or OS2), which has a 9µm core ...

Yellow is the universally adopted TIA color code for OS2 (Single Mode) fiber because it offers the lowest intrinsic fiber optic attenuation and is used for the longest reach.
