A duplex fiber connector is a type of fiber optic connector used to join two optical fibers together. It is designed to provide a secure connection and prevent light from escaping. The connector consists of two parts, a male and a female, which are joined together by a locking mechanism. The male connector has two pins that fit into the female connector, while the female connector has two holes that the pins fit into. The connector is designed to be easy to install and provide a reliable connection. It is commonly used in telecommunications and data networks.
