Cable managers are provided. A cable manager includes a body configured to be selectively engaged with a loose end of a first cable, wherein the body defines an effective unbiased length, as measured in an unbiased state, and an effective biased length, as measured in a biased state, and wherein the effective biased length is greater than the effective unbiased length.

A cassette for optical fiber includes one or more optical sensors. The cassette has a spool for handling optical fiber. An adjustable shaft is disposed such that the spool is configured to rotate about the adjustable shaft. The adjustable shaft is configured to handle spools having different diameters. A spool controller is coupled to the adjustable shaft and configured to rotate the adjustable shaft to perform one or more of extract and retract the optical fiber. One or more bushings are disposed proximate the spool and are configured to prevent the optical fiber from jumping off the spool.

An optical fiber enclosure has a housing having a mounting wall within a storage space. The enclosure also has a backplate attached to the mounting wall, the backplate having a mounting surface and a circumferential wall for receiving cable slack. The optical fiber enclosure also has a spindle attached to the mounting surface of the backplate, the spindle configured to connect to a cable spool configured to rotate relative to the spindle and the backplate to store optical fiber.

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.

A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.

Example telecommunications apparatus (100) include an enclosure (103) having an enclosure base (101) and a enclosure cover (102) that join together at a sealed interface. The enclosure cover (102) is latchable to the enclosure base (101). A splice tray assembly (106) is disposed within the interior (104) of the enclosure (103). The splice tray assembly (106) includes splice trays (150) mounted to a manager insert. A splitter (192) may be provided on the manager insert. The manager insert also may include a groove plate (160) latched to a base plate (180). One or more port assemblies (107-109) enable cables to enter and/or exit the enclosure (103) through sealed cable ports (145-147). The port assemblies (107-109) may provide anchors (214, 234) for cable strength members and/or organizers (243, 244, 253, 254) for fiber tubes.

An adapter assembly includes a single-piece or two-piece multi-fiber adapter defining a recess at which a contact assembly is disposed. The adapter assemblies can be disposed within adapter block assemblies or cassettes, which can be mounted to moveable trays. Both ports of the adapters disposed within adapter block assemblies are accessible. Only one port of each adapter disposed within the cassettes are accessible. Circuit boards can be mounted within the block assemblies or cassettes to provide communication between the contact assemblies and a data network.

A cable enclosure assembly includes an enclosure, a cable spool and a length of fiber optic cable. The enclosure defines an interior region, a first opening and a second opening aligned with the first opening. The first and second openings provide access to the interior region. The cable spool is disposed in the interior region of the enclosure and is rotatably engaged with the enclosure. The cable spool includes a drum and a flange engaged to the drum. The flange has an outer peripheral side, a cable management portion and an adapter bulkhead portion. The adapter bulkhead portion extends outwardly from the cable management portion and forms a portion of the outer peripheral side. The length of the fiber optic cable is dispose about the drum of the cable spool.

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.

An object is, in a pluggable optical module, to compactly house an optical fiber used for connecting optical components in a housing in which a plurality of optical components are mounted. The pluggable optical module (100) includes: a plurality of optical components, a printed circuit board (51); one or more optical fibers; and optical fiber housing means (14). All or a part of the plurality of optical components are mounted on the printed circuit hoard (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 he 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).
