A fiber optic cassette including a body defining a front and an opposite rear and an enclosed interior. A cable entry location is defined in the body for a cable to enter the interior of the cassette. The cable which enters at the cable entry location is attached to the cassette body and the fibers are extended into the cassette body and form terminations at connectors. The connectors are connected to adapters located at the front of the cassette. A front side of the adapters defines termination locations for cables to be connected to the fibers connected at the rear of the adapters. A cable including a jacket, a strength member, and fibers enters the cassette. The strength member is crimped to a crimp tube and is mounted to the cassette body, allowing the fibers to extend past the crimp tube into the interior of the cassette body. A strain relief boot is provided at the cable entry location.

All or a part of the plurality of optical components are mounted on the printed circuit board (51). One or more optical fibers connect between the plurality of optical components. The optical fiber housing means (14) includes a guide that is disposed on a plate-like member and can wind the one or more optical fibers, and mounted to be stacked with the printed circuit board (51) on which the optical components are mounted and all or a part of optical components other than the optical components mounted on the printed circuit board (51).

The disclosed system may include (1) a drive subsystem that translates along a powerline conductor, (2) a rotation subsystem that rotates a segment of fiber optic cable about the powerline conductor while the drive subsystem translates along the powerline conductor such that the segment of fiber optic cable is wrapped helically about the powerline conductor, and (3) an extension subsystem that (a) mechanically couples the rotation subsystem to the drive subsystem, and (b) selectively extends the rotation subsystem away from the drive subsystem and the powerline conductor to avoid obstacles along the powerline conductor. Various other systems and methods are also disclosed.

The present disclosure relates to a fiber optic closure which comprises a tray, a fiber optic adapter arranged on the tray, an output fiber optic connector and an input fiber optic connector inserted into both sides of the fiber optic adapter, and a fiber optic management device configured to accommodate an overlength portion of an output fiber optic connected to the output fiber optic connector. The fiber optic management device comprises a closure fixing part and a fiber optic storage which are mutually connected, the closure fixing part being provided for fixing the fiber optic storage into the fiber optic closure and the fiber optic storage being provided for accommodating the overlength portion of the output fiber optic. The present fiber optic management device can individually store the overlength portion of each of the internal optical fibers, thereby preventing the problem of stacking and entanglement of a plurality of internal optical fibers. In addition, the present fiber optic management device can be placed inside the fiber optic closure and no change needs to be made to the internal structure of the existing fiber optic closure.

A reel enclosure includes a base and a door pivotally coupled with the base. The door is movable between a first closed position and a second open position and is configured to hold a reel at an interior surface of the door. The reel is configured to have cable wound thereon. In the first closed position, the base is configured to prevent the reel from rotating relative to the door and the base, and, in the second open position, the door is configured to hold the reel outside of an interior of the base and permit the reel to rotate relative to the door and the base.

A telecommunications assembly includes a chassis defining an interior region and a tray assembly disposed in the interior region. The tray assembly includes a tray and a cable spool assembly. The cable spool assembly is engaged to a base panel of the tray. The cable spool assembly is adapted to rotate relative to the tray. The cable spool assembly includes a hub, a flange engaged to the hub and an adapter module. The flange defines a termination area. The adapter module is engaged to the termination module of the flange. The adapter module is adapted to slide relative to the flange in a direction that is generally parallel to the flange between an extended position and a retracted position.

An optical fiber distribution sub-frame including a base plate, two opposite sides of which are each provided with a mounting point position; a bracket, which is detachably mounted at the mounting point position on any side of the base plate; and an optical fiber channel tray, which is hinged to the bracket. When the bracket is mounted at the mounting point positions on different sides, the optical fiber channel tray is reversed along with the bracket. When the bracket changes position, the optical fiber channel tray connected to the bracket can be reversed together, so that the bracket and the optical fiber channel tray can be replaced from one side of the base plate to the opposite side, and after reversing, the base plate can be replaced from one rotation direction to the other relative to the optical fiber channel tray. One sub-frame can meet two different usage scenarios of left-hand rotation and right-hand rotation through disassembling and reversing, without the need to prepare two types of sub-frames, reducing stocking inventory, thereby saving time and costs. In addition, a method for reversing the orientation of the bracket and the optical fiber channel tray is as described above.

A telecommunications apparatus that includes an enclosure. The enclosure includes a housing with a plurality of fiber optic adapters. The fiber optic adapters are carried within the housing and include outer ports accessible from outside the enclosure and inner ports accessible from inside the enclosure. A fiber management tray is positioned within the housing includes a fiber management spool. A plurality of optical fibers which have connectorized ends are plugged into the inner connector ports of the fiber optic adapters. The optical fibers are routed about at least one of the fiber management spools.

An optical fiber distribution element (1810) includes a chassis (1820), an optical device (1900) mounted to the chassis (1820), the optical device (1900) including a plurality of cables (2134) extending from the optical device (1900) into the chassis (1820), and a cable management device (2110/2210) mounted to the chassis (1820). The cable management device (2110/2210) includes a plurality of radius limiters in the form of spools (2132/2232) in a stacked arrangement for managing the cables (2134) extending from the optical device (1900) for further connection within the chassis (1820), wherein a first of the spools (2132/2232) defines a spool wall (2136/2236) having a different wall length than that of a second of the spools (2132/2232), wherein a first of the plurality of cables (2134) is routed around the first of the spools (2132/2232) and a second of the plurality of cables (2134) is routed around the second of the spools (2132/2232) that has a different spool wall length than that of the first of the spools (2132/2232).

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.
