Typically, the housing is made of plastic. (Some connector styles are metal. Ferrule – A critical component of the connector, the ferrule holds the optic fiber in place and aids in. Nearly all types of fiber optic connectors have the following components: Connector housing – Sometimes called the connector body or external housing, the housing is the largest portion of the connector and holds the ferrule. They come in various types like SC, LC, ST, and MTP, each designed for specific. The function of fiber optic connectors is to align and connect two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or any other fiber optic component. The connectors can be put on patchords, pigtails or components with single-mode (SM). Plastic optical fiber (POF) cables are made from light-conducting plastics, polymers, and acrylics, are typically used for short, low-speed data links and illumination, and are renowned for their ease of installation, low cost, and flexibility. Plastic Optical Fiber Connectors Molex offers fully. While there are a wide variety of connector types around (see below), all connectors share these 3 common components: 1. - Ferrule: this is a thin structure (often cylindrical) that actually holds the glass fiber.
