  "description_excerpt": "The present disclosure relates generally to fiber optic systems and devices. More particularly, the present disclosure relates to devices and systems for mounting fiber optic components to fiber management trays or other structures.\n\nOptical fiber distribution systems may include equipment such as fiber management trays that are mounted in telecommunications enclosures or at other locations. A typical fiber management tray includes fiber routing paths for allowing excess length of optical fiber to be stored in looped configurations without violating minimum bend radius requirements for the optical fiber. Fiber optic components such as holders for holding fiber optic fusion splices, passive optical splitters, wavelength division multiplexers and the like are often mounted to fiber management trays. Improved structures are needed for connecting and releasing fiber optic components such as holders to and from structures such as fiber management trays or other structures.\n\nTeachings of the present disclosure relate to a mechanical connection interface that can allow for simple and reliable connecting and releasing of optical components. In certain examples, the connection interface can be easily interlocked in an intuitive manner. In certain examples, the connection interface is configured to allow a latch of the interface to be flexed down from a latching position to an unlatched position by laterally moving a component desired to be latched, as compared to requiring the latch to be directly pressed down.",
