An MPO connector (Multi-fiber Push-On) is a type of fiber optic connector that supports multiple fibers in a single ferrule. It is commonly used in high-density environments such as data centers and telecommunications infrastructure. These connectors are found primarily in data center environments for consolidating multiple fibers in backbone cabling and supporting parallel optics applications that transmit and receive. A fiber-optic adapter — sometimes called a coupler or bulkhead coupler — is a passive mechanical interface that mates and aligns two terminated optical fibers (i. It is characterized by a rectangular ferrule with a nominal diameter of 6. Instead of plugging 12 separate LC duplex connectors, you can mate one MPO.
