A high-density fiber cassette and enclosure for installing the cassette are part of a cable management system. The cassette provides a more efficient design enabling installation of additional fiber connecter adapters, thus resulting in high fiber connector density within a given RU space.

A telecommunications rack system includes a first element defining splice locations and a second element defining adapters for receiving connectorized cabling, wherein the first and second elements are positioned on the same rack. A first end of a fiber optic pigtail is spliced at and extends from the splice locations of the first element. A second end is connectorized with a fiber optic connector that is coupled to an adapter of the second element. The pigtail extends between the first and second elements. A cable manager is removably mounted at the side of at least one of the first and second elements. The cable manager defines a U-shaped passage including ends that open toward one end of the elements and a closed end opposite the open ends. The U-shaped passage defines cable pass-throughs adjacent the closed end for transitioning cables from inside the U-shaped passage to an exterior thereof, wherein the connectorized pigtail is passed at least through a portion of the U-shaped passage and out the cable pass-through going from the first element to the second element.

An adapter structure for fixing a portion of a telecommunications cable to a telecommunications device and directing fibers within the cable into the device includes a crimp body and an outer mounting body. The crimp body defines a first side and a second side separated by a center portion and also includes two flexible legs extending from the first side and an integral crimp portion extending from the second side that has outer surface texturing. The outer mounting body includes a through-hole, where the two flexible legs of the crimp body fit into one end of the through-hole. It also includes tabs on opposing sides of the outer mounting body for slidable insertion into slots defined by the telecommunications device to prevent movement of the outer mounting body in a front to back direction, relative to the device.

A fiber optic connector arrangement includes a printed circuit board coupled to a connector housing. The printed circuit board includes a memory storage device that is configured to store physical layer information pertaining to the fiber optic connector arrangement. The printed circuit board also defines contacts that are electrically coupled to the memory storage device to enable the physical layer information to be read from the memory storage device by a media reading interface. A connector assembly includes at least one adapter assembly; a printed circuit board; and a media reading interface. The connector assembly also may include a tactile pressure sensor. The adapter assembly defines at least a first port and a second port that are configured to connect optical fibers of two connector arrangements. One or more connector assemblies can be mounted to a fiber panel system.

A hinge structure (2202) for pivotally mounting a first telecommunications element (2256) to a second telecommunications element (2224/2210) includes a hinge pin (2203) provided on the first element (2256) and a hinge pin receiver (2204) provided on the second element (2224/2210). The hinge pin (2203) defines a notch (2206) separating the pin (2203) into two pin halves (2205). The hinge pin receiver (2204) defines two sets of opposing surfaces (2214), the two sets (2214) separated by a divider (2212), the divider (2212) configured to be accommodated by the notch (2206) when the hinge pin (2203) is inserted into the hinge pin receiver (2204), wherein each opposing surface set (2214) defines a slot (2213) for receiving each pin half (2205).

A cabinet unit for use in an optical fiber distribution system may include a housing having a cavity, a plurality of extension portions contained within the housing, each extension portion being adapted to support an adapter for receiving cables aligned lengthwise with the extension portion, and a support structure formed on an inner surface of the housing, each extension portion being mounted to the housing by the support structure and extends away from the inner surface of the housing. The plurality of extension portions may be hingedly coupled to the support structure. A clearance between two adjacent extension portions of a given support bar may be configured to be adjusted by rotating the adjacent extension portions along their respective hinged connections.

A telecommunications device includes a rack defining right, left, front, rear, top, and bottom sides, the rack defining mounting locations in a stacked arrangement from the bottom to the top, the mounting locations for receiving modules defining connection locations. A cable storage bay is located at one of the right and left sides of the rack and defines front and rear cable storage areas. Both the front and rear cable storage areas include cable management structures for managing and guiding cables toward and away from the connection locations. A trough is defined at the top of the rack, the trough configured for extending cables to other racks in a front to rear direction, the trough also defining a cable drop-off communicating with the cable storage bay for extending cables to either of the front or rear cable storage areas for further connection to the connection locations.

A telecommunications tray is presented herein. In some examples, the telecommunications tray assembly includes a tower structure and at least one hinged tray rotatably mounted to the tower structure. In one aspect, the hinged tray is rotatable between at least two indexed positions, wherein the hinged tray is positively retained in the at least two indexed positions by a position retention structure. In some examples, the position retention structure is a transversely mounted leaf spring that is received into recesses of the tower structure.

A telecommunications module includes an optical wavelength division multiplexer/demultiplexer configured to demultiplex a first optical signal input into the telecommunications module into a plurality of different wavelengths, a fiber optic splitter configured to split a second optical signal input into the telecommunication module into a plurality of optical signals, and a plurality of optical add/drop filters, each of the optical add/drop filters configured to combine one of the optical signals that has been split by the fiber optic splitter and one of the wavelengths that has been demultiplexed by the optical wavelength division multiplexer/demultiplexer into a combination output signal that is output from the telecommunications module.

An optical fiber distribution element includes a chassis defining an interior; a movable tray slidably movable from within the chassis to a position at least partially outside the chassis, the tray defining a front end and a rear end; a slide mechanism which connects the movable tray to the chassis; at least one hingedly mounted frame member within the tray which hinges about an axis perpendicular to the direction of movement of the movable tray; and a cover mounted adjacent the rear end of the tray and movable between an access position and an operational position when the tray is in the open position, only the operational position of the cover allowing the tray to move from the open position to the closed position, the access position al lowing access to the at least one hingedly mounted frame member, and the cover in the access position preventing the tray from moving from the open to the closed position.
