The present disclosure relates to a fiber optic assembly having a splice tray that increases spatial efficiency within the fiber optic assembly and within the splice tray. The splice tray may be inserted and/or removed from a terminal without utilization of tools. Additionally, the splice tray may be configured to enable one handed insertion or removal, which may be advantageous, such as in small terminals or confined spaces. The splice tray also provides an efficient routing pattern of optical fibers to enable larger diameter optical fibers to be routed within the splice tray and the terminal.

A connector box has a housing forming a space and a cover configured to provide access to the space, a plurality of connectors configured to enable selective connection of fiber optic cables within the enclosed space, and a drop cable entrance assembly configured to provide an opening for one or more drop cables to enter the space in the housing. The drop cable entrance assembly has a housing opening portion providing access to the space from an exterior of the housing and having a removable plate and a grommet, and a cable clamp portion configured to hold the one or more drop cables in place via contact pressure.

A cable restraint located in a splice enclosure to restrain a cable includes a tray having a bottom side with an upward facing surface. The cable restraint also includes a restraint bridge removably attached to the tray. The restraint bridge includes a central portion having a surface configured to cooperate with the tab feature to inhibit relative motion between the restraint bridge and the tray in a direction non-perpendicular to an axis of the cable. A restraint clip is removably attached to the restraint bridge and includes a restraint post attached to the body portion configured to secure a strength member of the cable to the restraint clip. The restraint clip further includes a column attached to the body portion configured to inhibit relative motion between the restraint clip and the restraint bridge in the direction non-perpendicular to the axis of the cable.

A wall box includes an enclosure having a base and a cover connected to the base. The base and the cover enclose an interior region. The wall box further includes a plurality of fiber optic adapters mounted to the enclosure. The fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure. A tray stack is mounted within the interior region. The tray stack includes a tray mount pivotally connected to the enclosure. The tray mount includes a top surface and an oppositely disposed bottom surface. A first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface. A plurality of trays is disposed in the first splice tray mounting area. A tray is disposed in the second splice tray mounting area.

Pairs of windows are cut into a distribution cable at various points along the length to couple some of the optical fibers of the distribution cable to drop cables. A wrap-type sealing arrangement can seal a first window of each pair. An enclosure-type sealing arrangement can seal a second window of each pair. The enclosure includes a splice tray and cable storage. Optical adapters and/or a passive splitter also may be disposed within the enclosure.

A fiber optic distribution terminal includes a cable spool rotatably disposed within an enclosure; an optical power splitter and a termination region carried by the cable spool; an optical cable deployable from the enclosure by rotating the cable spool by pulling on a connectorized end of the optical cable; and splitter pigtails extending between the optical power splitter and the termination region. One fiber of the optical cable extending between the connectorized end and the splitter input. The other fibers of the optical cable extend to a multi-fiber adapter.

A fiber optic enclosure assembly includes a housing having an interior region and a bearing mount disposed in the interior region of the housing. A cable spool is connectedly engaged with the bearing mount such that the cable spool selectively rotates within the housing. A termination module disposed on the cable spool so that the termination module rotates in unison with the cable spool. A method of paying out a fiber optic cable from a fiber optic enclosure includes rotating a cable spool, which has a subscriber cable coiled around a spooling portion of the cable spool, about an axis of a housing of the fiber optic enclosure until a desired length of subscriber cable is paid out. A termination module is disposed on the cable spool.

A communication system may include a first chassis having first and second side walls and adapted to slidably receive therein a plurality of cassettes. A first cable hanger assembly may have a first side edge hingedly coupled to the first side wall of the first chassis, the first cable hanger assembly including a plurality of first hangers adapted to support cables thereon. An axis of rotation of the first cable hanger assembly may be substantially orthogonal to a direction in which the plurality of cassettes are slideable. The cable hanger assembly may be rotatable from a first position to a second position so that during rotation from the first position to the second position, the plurality of first hangers move toward front faces of the plurality of cassettes.

A bladed chassis system facilitates installation of the bladed chassis system and replacement of the blades at the chassis. Blades can be inserted and removed from the front and/or the rear of the bladed chassis system at the discretion of the user. Blades can be moved between discrete positions. In examples, blades can be one-handedly released from the chassis to allow movement between discrete positions. In examples, accidental movement past a discrete position is inhibited. Accidental removal of the blades from the chassis is inhibited. The chassis and blades cooperate to manage the optical fiber cables routed through a cable port in the chassis to the blades.

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.
