A flange is a physical shoulder integrated into the adapter housing. Its function is to create a hard stop against the panel surface, limiting axial movement during installation and service. Flangeless adapters rely entirely on panel cutout tolerance and external fasteners or clips. An optical fiber flange is a type of optical fiber connector used to attach optical fiber cables to other equipment, such as patch panels or network switches. It is designed to provide a secure and reliable connection between optical fibers, minimizing signal loss and ensuring high-quality. The Fiber Optic Flange, also known as a Fiber Optic Adapter or Fiber Optic Coupler in engineering, is one of the most fundamental and essential passive devices in fiber optic communication systems. Duplex cables are fiber optic cables with two optical fibers.
