Analysis of the Function of Fiber Optic Couplers
A fiber coupler is a passive optical device that manages the flow of light signals within an optical network. It functions by dividing a single incoming light path into multiple outgoing paths, or by combining light from several input paths into a single output fiber. SC Fiber Optic Connector: SC stands for Square Connector or Subscriber Connector. It was developed by Nippon Telegraph and Telephone (NTT) company. Optical fiber couplers generally have the following characteristics: First, the device is composed of optical fiber, which is an all-fiber device; second, the demultiplexing and. To this end, the Large-Beam Fiber Coupler (LBFC) with a Double-combined Collimating Lens (DCL) and a single-mode TEC fiber structure are proposed in this study.
