Abstract: An outdoor communication cabinet includes a housing having a interior, an opening into the interior and a door connected to the housing at the opening that includes a first aperture and a first fan tray with a plurality of fans, the fan tray being hingedly connected to the door for movement between first and second positions relative to the first aperture. Also a method of detecting blockage of filters in a communication cabinet.

Abstract: A cable organization unit includes a housing. A tray is attached to the housing by at least one slide, and is movable between a first position and a second position relative to the housing. A hood is removably secured to the tray. A user may remove the hood from the tray to access adapters attached to a bulkhead on the tray. The tray may include a latch for securing the tray to the housing in the first position, and the hood may be removed from the tray while the tray is in the first or second positions. A retainer is optionally attached to the housing. The retainer includes an adjustable opening which may be reduced in size such that edges of the opening frictionally engage and hold a jacket of a cable passing therethrough.

Abstract: An outdoor equipment cabinet includes a housing with an equipment compartment therein. An intake air vent and an exit air vent are formed in the housing. A fan is mounted within the housing for pulling air into the intake air vent, moving an air stream through the equipment compartment, and pushing air out of the exit air vent. A membrane is disposed adjacent the intake air vent. The membrane allows air to pass therethrough, but resists the passage of water and contaminants therethrough. In some embodiments, a baffling plate is disposed to direct the air stream within the equipment compartment, and/or the fan speed is controlled by a temperature sensor, and/or a clogging of the membrane is monitored and reported, and/or the intake air vent is located in a first door and the exit air vent is located in a second door of the cabinet.

Abstract: An outdoor equipment cabinet includes a housing with a first door for accessing an equipment compartment within the housing. A battery compartment is located proximate a bottom of the housing. First and second air vents are located in an upper half of the cabinet. At least one fan moves air from the first vent, down to the battery compartment and then up and out of the second vent. In some embodiments, the first door includes the second vent, and a dual wall construction leading to a heat exchanger mounted to the first door. Air passes through the dual wall construction of the first door and through the heat exchanger to regulate an air temperature within the equipment compartment, and then passes out the second vent. The first vent may be provided in a second door which also includes a dual wall construction to guide incoming air to the battery compartment.

Abstract: A flame suppression cabinet for printed circuit boards includes intumescent material that expands at an elevated temperature to block ventilation openings in a top panel. Fire suppression plates are positioned between adjacent ones of a plurality of printed circuit boards positioned vertically on a shelf rack in side-by-side spaced-apart parallel relationship to prevent fire from spreading between the circuit boards.

Abstract: A splice tray for use in splicing fiber optic cables has an outer periphery and a cable splicing area inwardly of the outer periphery. A main cable guideway for receiving a pair of side-by-side cables to be spliced extends along a portion of the outer periphery adjacent thereto. The main cable guideway splits into first and second continuation guideways, the first of which curves inwardly from the outer periphery to intersection with the splicing area from one direction. The second continuation guideway continues along another portion of the outer periphery to intersection with the splicing area from another direction. The two fiber optic cables that extend along the main guideway are separated to extend through the first and second continuation guideways to the splicing area for being joined together in a splice. A cable looping device is provided in the splicing area for receiving cable loops to take up slack, and a splice receiving recess is provided in the splice area for holding a splice.

Abstract: An outside plant equipment enclosure for housing telecommunications equipment, which normally operates when the equipment enclosure is closed, is provided. The enclosure includes an internal compartment for storing telecommunications equipment, at least one opening in the internal compartment and a hydrophobic material. The at least one opening defines substantially the entire area of the internal compartment which is open to an outer atmosphere when the telecommunications equipment is normally operating. The hydrophobic material entirely covers every opening of the at least one opening.
