The number of network connections in data centers is on the rise. Data centers have to achieve ultra- high density in cabling to accommodate all this cabling in the first place. Multimode fiber optics is the medium of the future for satisfying the growing need for transmission speed and data volume over short distances. New multi-fiber connectors bring together 12 or 24 fibers in a single interface just as compact as an RJ45 connector. The multi-fiber push-on (MPO) technology and especially the MTP® connectors (US Conec) in connection with Elite ferrules have proven to be a practical solution. The MPO connector is a multi-fiber connector, due to its modularity, offers installers and operators reduced time & effort for installations, modification and maintenance of a structured communication cabling for today’s and future demands of data centers.
