A parallel optical interface is a form of fiber-optic technology aimed primarily at communications and networking over relatively short distances (less than 300 meters), and at high bandwidths. Instead of relying on a single fiber to carry a high-speed serial signal, this technology divides the data stream into several lower-speed channels that run simultaneously across multiple fibers. POIs differ from traditional fiber optic communication in that data is simultaneously. Multimode fiber optics is the medium of the future for satisfying the growing need for transmission speed and data volume over short distances. Using laser-optimized multimode fiber (LOMMF), serial.
