Abstract: A telecommunications chassis comprises a cable sealing portion defining at least one cable opening configured to sealably receive a cable and a module mounting portion extending from the cable sealing portion, which further comprises a housing defining an open front closable by a door to define an interior, a rear wall, a right wall, and a left wall. A plurality of module mounting locations is provided in a vertically stacked arrangement, each configured to receive a telecommunications module through the open front. An exterior of the housing includes a first column of radius limiters defining curved profiles for guiding cables from the front toward the rear with bend control. A second column of radius limiters in the form of spools is spaced apart and generally parallel to the first column of radius limiters and a third column of radius limiters, at least some of which are in the form of spools, is also spaced apart and generally parallel to the first and second columns of radius limiters. The rear wall defines an opening for accessing from the exterior of the housing rear ends of modules to be mounted in the housing for signal input, wherein the exterior also includes a plate at least partially overlapping the opening for protection of cables entering the opening.

Abstract: Systems and methods for delivering multiple passive optical network services are disclosed. One system includes a first optical transmission service comprising a common wavelength pair routed from a source to each of a plurality of subscribers and a second optical transmission service comprising a plurality of unique wavelength pairs, each of the unique wavelength pairs assigned to a subscriber among the plurality of subscribers. The system includes a splitter optically connected to first fiber carrying the first optical transmission service, the splitter including a plurality of outputs each delivering the first optical transmission service, and a wavelength division multiplexer connected to a second fiber, the wavelength division multiplexer separating each of the unique wavelength pairs of the second optical transmission service onto separate optical fibers. The system further includes a plurality of second wavelength division multiplexers optically connected to a different output of the plurality of outputs of the splitter and to a different one of the unique wavelength pairs from the wavelength division multiplexer, thereby combining a unique wavelength pair and a common wavelength pair onto a single fiber to be delivered to a subscriber.

Abstract: A fiber optic cassette may include a cassette body defining a front end, a rear end, and an enclosed interior. Multiple identical apertures are included on the front end of the cassette body, where each aperture is configured to accept a fiber optic adapter. The cassette may further include an optical component located in an enclosed interior of the cassette body and configured to process a signal received from a fiber optic connector coupled to one of the fiber optic adapters, a crimp tube mounted to the front end of the cassette body, and at least one fiber optic cable attached to the crimp tube, extending from the cassette and configured to carry the signal processed by the optical component. The fiber optic cable may include a jacket, a strength member crimped to the crimp tube, and optical fibers extending past the crimp tube into the interior of the cassette body, wherein the mounting structure for mounting the crimp tube to the cassette body is receivable within one of the identical apertures.

Abstract: A fiber optic telecommunications device includes a frame and a fiber optic module including a rack mount portion, a center portion, and a main housing portion. The rack mount portion is stationarily coupled to the frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction. The main housing portion of the fiber optic module includes fiber optic connection locations for connecting cables to be routed through the frame. The center portion of the fiber optic module includes a radius limiter for guiding cables between the main housing portion and the frame, the center portion also including a latch for unlatching the center portion for slidable movement. Slidable movement of the center portion with respect to the rack mount portion moves the main housing portion with respect to the frame along the sliding direction.

Abstract: A cable assembly for optical monitoring is assembled by laying optical fibers into an adhesive layer on a substrate to form an optical circuit. First ends of the fibers are arranged in various groups and second ends of the fibers are arranged in various groups. Groups at a first end of the circuit are spliced to coupler input fibers and coupler output fibers. Groups at the second end of the circuit are terminated at one or more input connectors, one or more output connectors, and one or more monitoring connectors. Some cable assemblies monitor signals received at the input connectors. Other cable assemblies monitor signals received at both the input connectors and the output connectors.

Abstract: A telecommunications module defines an interior with separate right and left chambers. An optical component is housed within the left chamber. Signal input and output locations are exposed to the right chamber. The right chamber allows excess fiber to accumulate without bending in a radius smaller than a minimum bend radius. A dual-layered cable management structure is positioned within the right chamber that defines a lower cable-wrapping level and a separate upper cable-wrapping level. The upper cable-wrapping level is defined by a removable cable retainer mounted on a spool defining the lower-cable wrapping level. Cabling carrying the input and output signals are passed between the right and left chambers before and after being processed by the optical component.

Abstract: A fiber optic telecommunications device includes a fiber optic cassette comprising a body defining a front and an opposite rear and an enclosed interior. A fiber optic signal entry location is defined on the body for a fiber optic signal to enter the interior via a fiber optic cable. An adapter block defines a plurality of fiber optic adapters and is removably mounted to the body with a snap-fit interlock, each adapter including a front outer end, a rear inner end, and internal structures allowing mating of optical connectors mounted to the front and rear ends, respectively. A removable spacer is mounted to the body, the spacer configured to expand the size of the enclosed interior of the cassette and a removable cover is mounted to the spacer. Connectorized optical fibers extend from the fiber optic signal entry location to the rear inner ends of at least some of the fiber optic adapters for relaying the fiber optic signal to fiber optic connectors to be coupled to the front outer ends of the adapters.
