MPOs or multi-fiber push on connections, are fiber connectors made up of several optical fibers. MPO Connectors are generally available with 8, 12, or 24 fibers for popular data center and LAN applications, despite being described as an array connector with more than 2 fibers. There are other fiber counts available, such as 32, 48, 60, or even 72 fibers, however they are normally utilized for specialized extremely high-density multi-fiber arrays in large scale optical switches.
