Terminal enclosure with modular aspects and modules for interfacing with the terminal enclosure

Abstract

Aspects of the present disclosure relate to a modular fiber optic distribution system for enhancing installation flexibility and for facilitating adding components to a terminal housing over time so as to delay cost. The system is configured to allow components (e.g., inserts, add-on modules, etc.) to be readily added to the terminal housing over time to expand capacity, provide upgrades and to provide forward and backward compatibility.
