Introduction
A Multi-Fiber Push On (MPO) connector is a type of optical fiber connector used in high-speed data transmission applications. It is widely used in data centers, telecommunications, and other industries because of its high-density and high-bandwidth capabilities. The MPO connector is made up of several components that work together to ensure a secure and efficient transmission of data. In this article, we will explore the different parts of the MPO connector in detail.
Connector Housing
The connector housing of the MPO connector is the outermost part that holds all the internal components. It is a rectangular-shaped shell made up of plastic material such as polycarbonate or ABS. The housing is designed to protect the internal components from physical damage and dust. The housing comes in different colors, including beige, black, and blue, to help users easily identify different types of connectors.
Ferrule
The MPO connector uses a ferrule to align the optical fibers and hold them in place. The ferrule is a small cylindrical-shaped component made up of ceramic or metal. It has a tiny hole in the center that allows the optical fibers to pass through. The ferrule is designed to provide a precise connection between the optical fibers, ensuring minimal signal loss. The ferrule size varies depending on the number of optical fibers in the connector. For example, a 12-fiber MPO connector has a larger ferrule than an 8-fiber MPO connector.
Optical Fiber
The optical fiber is the most crucial component of the MPO connector. It is a hair-thin filament made up of glass or plastic material that carries information in the form of light. The optical fibers are arranged in a parallel fashion, and their ends are cut at an angle to ensure a smooth connection with other optical fibers. The optical fibers are color-coded to help users easily identify them based on their function.
Boot
The boot is a small rubber or plastic component that covers the ferrule and protects it from physical damage. It is designed to create a strain relief that reduces stress on the optical fibers when they bend. The boot also helps users easily grip the connector and plug and unplug it from the port. The boot comes in different colors and shapes, including round and square, to help users identify different types of connectors.
Guide Pins
The guide pins of the MPO connector are small metal or plastic components that help align the connector with its corresponding port. They ensure that the connector is inserted into the port in the correct orientation and prevent the optical fibers from getting damaged. The guide pins are located on the sides of the connector and fit into corresponding holes on the port.
Polishing
The MPO connector employs a polishing process to provide a high-quality end-face finish on the ferrules. The polishing process involves rubbing the ferrule against a polishing pad using a special polishing film. The process creates a smooth and flat surface that reduces signal loss and increases reliability. The polishing process also helps remove any dirt or debris from the ferrule surface to ensure optimal performance.
Conclusion
The Multi-Fiber Push On (MPO) connector is a critical component in high-speed data transmission systems. It allows multiple fibers to be connected in a single simple plug and play format. Understanding the different parts of the MPO connector is essential for building and maintaining high-performance data transmission systems. The connector housing, ferrule, optical fibers, boot, guide pins, and polishing all play a vital role in ensuring a secure and efficient transmission of data.
