Patent attributes
Disclosed are fiber optic assemblies for handling mini duplex connectors (MDC) including a rack-mountable chassis, independent sliding trays disposed in the chassis, and a plurality of MDC modules removably installable in the sliding trays. Each MDC module includes protruding features configured to interact with tray guides having corresponding features that permit vertical installation of the modules in the trays while preventing horizontal translation and rotational motion of the installed MDC modules. MDC modules may have various configuration, for instance MTP module, patching module and pre-terminated tailed module configurations. The assemblies and components disclosed herein maximize connections densities of MDC connectors while improving access thereto in high density applications.
