Claim 0:
1. A method of forming a color-coded mark on an optical fiber having an outer surface and a center line that defines an axial direction of the optical fiber, comprising:
forming two or more continuous ink streams that reside substantially in a row and in close proximity to one another, with at least first and second ones of the two or more continuous ink streams having first and second colors that are different from one another;
moving the optical fiber in a first direction over a fiber path that resides adjacent the two or more continuous ink streams, the moving optical fiber not intersecting the two or more continuous ink streams as the two or more continuous ink streams are flowing; and
causing the moving optical fiber to simultaneously intersect the first and second ones of the two or more continuous ink streams to respectively form first and second axially spaced apart marks on the outer surface of the optical fiber, the first and second axially spaced apart marks respectively having the first and second colors of the first and second continuous ink streams.
