Abstract

An optical fiber distribution cabinet includes at least three separate, vertically arranged areas of optical fiber functionality; namely a coupler module storage compartment, a fiber slack storage compartment, and a fiber connection compartment with the fiber slack storage compartment disposed laterally between the coupler module storage compartment and the fiber connection compartment. A plurality of pre-connectorized (pigtail or jumper) coupler module output fibers are routed from the coupler module storage compartment through the fiber slack storage compartment to the fiber connection compartment and interconnected with corresponding optical fibers of one or more pre-connectorized distribution cables. At least one coupler module input fiber is spliced directly to an optical fiber of a feeder cable. Alternatively, the coupler module input fiber is routed from the coupler module storage compartment through the fiber slack storage compartment to the fiber connection compartment and interconnected with a corresponding optical fiber of a pre-connectorized feeder cable.
