    The LC connector (left), which features a smaller ferrule size and latch mechanism, is ideal for high-density patch applications within the fiber-to-the-home (FTTH) space. However, to support more fibers in individual ferrules, the industry introduced the multiple fiber push-on/pull-off (MTP/MPO) connector, which can support up to 24 fibers in a single ferrule for use in high-density environments like data centers. But MTP/MPO connectors must be mated to an opposing male (center) or female (right) connector, which can lead to higher inventory costs.
