The majority of our customers manufacture fiber optic cable assemblies, which are widely known as patch cords.

Patch cords can be simplex or duplex.

  • A simplex cable consists of a single strand of optic fiber.
  • A duplex cable is composed of two insulated single-conductor optic fibers.


(We encourage you to review the Fiber Optic Center Glossary to familiarize yourself with the wide range of industry terminology.)
