A cable management unit including a support assembly for mounting a patch panel, such as to a wall. The support assembly may include first and second anchor members adapted to be anchored to the wall, and first and second support arms hingedly coupled to the first and second anchor members at first and second hinge points, respectively. The first and second support arms may be adapted to be coupled to the patch panel. A chassis the patch panel may be supported by the first and second support arms. The first and second support arms may be configured to pivot about the first and second hinge points respectively between storage and access positions. The first and second support arms may extend outward from the wall in the access position and may be substantially parallel to the wall in the storage position.

An object is to provide a closure with a structure having a drainage function to eliminate water immersion into a coated optical fiber against temporary flooding and to prevent water from continuously contacting the coated optical fiber. Another object is to provide a closure with improved workability for opening and closing.

A closure according to the present invention protects a connection part that connects a coated optical fiber enclosed in a optical fiber cable with a coated optical fiber enclosed in a optical fiber cable. The closure includes a coated optical fiber housing that divides an interior of the closure into a first space that is on a side of a road and has a main body cable insertion hole for inserting the optical fiber cables from an exterior and a second space that is on an opposite side of the road and includes the connection part. The coated optical fiber housing has a frustum shape with two bases each open and a base with a smaller area of the two bases protruding toward the side of the road. The base with the smaller area of the two bases is a cable insertion hole for inserting the optical fiber cable from the first space into the second space and is not in contact with a bottom surface of the first space on the side of the road.

Fiber pistoning apparatus and methods of use are provided. A fiber anti-pistoning apparatus includes an axial centerline, and an elongate main body that at least partially surrounds the axial centerline and extends from a first end to a second end of the elongate main body. The elongate main body defines a channel that extends along the axial centerline for housing a bundle of fibers. The channel extends between a first opening at the first end, a second opening at the second end, and a slotted opening between the first end and the second end for receiving the bundle of fibers. The elongate main body includes one or more retention features for coupling to a first buffer tube.

A locking system for a utility vault including an I-beam extending across an opening in utility vault, a two-piece lid positioned in the opening over the I-beam, brackets positioned on opposite ends of each piece of the two-piece utility lid for engaging an inside wall surface of the utility vault and the I-beam, and a three-tier locking system positioned at an end of one piece of the two-piece lid to lock the lid to the vault including a L-bolt lock, a padlock and a lockable door on an upper surface of the lid.

Closure-mounted support structures and associated assemblies for supporting fiber optic management devices within a fiber optic closure defining a closure volume. The support structures are adapted to receive and hold axially distal portions of protection tubes that hold and protect portions of optical fibers as they are routed through the closure volume, and also to support optical fiber management trays into which the optical fibers can be routed upon exiting the protection tubes.

A stubbed terminal housing for fiber optic cable management in a utility vault or pedestal housing having a body portion, a cavity within the body portion, a plurality of fiber optic fiber ports extending from the body portion for entry and exiting of fiber optic fibers, and a mounting portion extending from the body portion for attaching the stubbed terminal housing to the utility vault or pedestal housing.

The present disclosure relates to a utility enclosure that can store fiber optic cables that includes an underground enclosure and a cable storage system mountable to a wall of the enclosure. The cable storage system includes a cable storage wheel for storing the fiber optic cable, a mounting plate used to secure the cable storage wheel to the wall of the enclosure, and a spacer. The spacer has a first end secured to the mounting plate and a second end secured to the cable storage wheel for maintaining the cable storage wheel in a spaced relationship relative to the wall of the enclosure.

A feed device for supplying electrical power and/or data to an electrical load, which is movable in at least one travel direction relative to the feed device, via cables. An electrical line cable carried along by the electrical load can be connected or is connected to the feed device, and to a power supply system for supplying the movable electrical load. The line cable can be output or retrieved from a reservoir, which is carried along by the load, in accordance with a distance between the reservoir and the feed device. The feed device has at least one connection part, which is rotatable about at least one pivot axis, for the line cable. This feed device, as well as a power supply system having such a feed device, provides protective guidance and storage of the line cable, reducing the risk of kinking or excessive bending of the line cable when moving the electrical load.

A modular access chamber, shown generally at 1000, is suitable for providing access to underground services (not shown), such as telecommunications cable systems and the like, and is designed to be supplied in component form, for assembly on site. The chamber may be constructed to be of different depths and is generally rectangular in plan, comprising first and second types of connectable wall portions, 1100 and 1200 and a cover 1300.

The wall portions 1100 and 1200 interlock to form a substantially continuous perimeter wall, for example such that the wall portions 1100 each comprise a substantially C-shaped part of the perimeter of the completed access chamber, whereas the wall portions 1200 form substantially linear parts of the perimeter.

The cover 1300 has an integral tread pattern 1310 to provide a non-slip surface. It is also provided with fixing apertures 1320 for receiving fixings (not shown) to secure the cover to the wall portions beneath and lifting apertures 1330 for receiving a lifting tool (not shown) which may be used to lift the cover from the access chamber to gain access to an interior.
