AFL has been using a proprietary process of fiber bundle separation inside stainless steel and plastic buffer tubes since 2005. Prior to using this method, AFL utilized striped (or dashed) marks on each individual fiber, but received many customer complaints that this method was not user-friendly. Each individual fiber had to be examined and segregated taking extra time and a keen eye. Therefore, AFL changed its process to be more user-friendly by incorporating colored string binders that follow the standard color code instead of stripes. Refer to this white paper for the process.
