    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.

    CPC classification number: H04J14/0245

    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.

    IPC: G02B6/44

    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.
