Custom Ferrules
Manufactured Ferrules to Receive Oversized Variable Fiber Diameters
Many applications require ferrules only, or not mounted into the ST, SC, FC or SMA style connectors. Select from our “Stock Ferrule Sizes” that we offer in four sizes below, which provides the best tolerances at no minimum purchase. If your fiber diameter size requirements are different, see Standard and Premium selections below.
