    What is the interface of the light-insertion module called

    The ROSA is composed of three main elements: a photodiode that detects incoming light signals, a protective housing made of either metal or plastic, and an electrical interface that facilitates the connection to communication equipment. An optical fiber connector is a device used to link optical fibers, facilitating the efficient transmission of light signals. They come in various types like SC, LC, ST, and MTP, each designed for specific. The fiber connector is called a fiber optic or optical fiber connector. The connector mechanically orients the fiber cores, allowing light to pass and travel through. One vital element in the data communication sector is the Small Form-factor Pluggable (SFP) module.
