A cable spool includes first and second curved flanges extending radially outwardly from first and second axial ends of a drum. The flanges have outer edges that cooperate to define an annular slot providing access to a passageway surrounding the drum. The slot has a width that is less than half the height of the drum. A cable is wrapped around the drum. A closure having an environmentally sealed interior may receive an end of the cable. A second cable can be deployed from a second spool and coupled to the end of the cable within the closure. The second spool can be mounted with the cable spool. A cover can be placed over the spools for aesthetic or protection reasons.

Unit for winding and unwinding cables of a cable-laying apparatus, comprising a reel to support the cables to be wound or unwound, a support frame configured to keep said reel in a raised position with respect to the ground, and a rotation shaft solid with the reel and associated with a corresponding hydraulic drive unit; the unit also comprises at least a dynamic braking device associated with the rotation shaft and configured to allow, according to a first operating mode, the normal rotation of the shaft and therefore of the reel for winding or unwinding the cables, and to exert on the shaft and therefore on the reel, according to another operating mode, a dynamic braking condition that allows the shaft to rotate in a braked configuration for at least a certain period of time and prevents the instantaneous stoppage of the rotation of the reel.

Aspects of the present disclosure involve a cable spool assembly. The cable spool assembly includes a first spool that is detachably coupled to a second spool by respective coupling features of the first spool and the second spool such that the first spool and the second spool are coaxially aligned.

A fiber optic cable spool is disclosed herein. The fiber optic cable spool may include a first radial flange located at a first axial end of the fiber optic cable spool, a second radial flange located at a second axial end of the fiber optic cable spool, and a drum that extends axially between the first and second radial flanges. The fiber optic cable spool may also include a storage compartment located within the drum. The first radial flange may define a first opening for accessing the storage compartment within the drum. The drum may have a circumferential drum surface that defines a second opening for accessing the storage compartment within the drum.

The present disclosure relates to the installation of transmission lines with a transmission line advancement system. The transmission line advancement system is configured to install a variety of transmission lines into a conduit, pipe, duct, or the like, including fiber optic cables and electrical transmission lines. In embodiments of the disclosure an advancement device for advancing a transmission line within a transmission line installation system, a method for advancing a transmission line using an advancement device, and another advancement device for advancing a transmission line within a transmission line installation system are disclosed.

A device that pulls out an optical fiber includes: a bobbin support that supports a bobbin rotatably about a rotation axis; a first pulling out unit that holds a first end of the optical fiber, pulls out a first portion of the optical fiber wound around the bobbin from a side of the first end in a state where the bobbin rotates in a predetermined direction, and returns a part of the first portion to the bobbin in a state where the bobbin rotates in a direction opposite to the predetermined direction; and a second pulling out unit that holds a second end of the optical fiber after the first pulling out unit pulls out the first portion from the side of the first end, and pulls out a second portion of the optical fiber wound around the bobbin from a side of the second end.

A storage unit includes a wound body made of wound linear material and a storage body that stores the wound body. The wound body includes a first spiral part in which the wound linear material is spirally wound in a first winding direction such that a distance between the wound linear material of the first spiral part and a center of the wound body gradually decreases, a first inversion part, disposed inside the first spiral part, that inverts a winding direction of the wound linear material from the first winding direction to a second winding direction opposite to the first winding direction, and a second spiral part, disposed outside the first inversion part, in which the wound linear material is spirally wound in the second winding direction such that a distance between the wound linear material of the second spiral part and the center gradually increases.

A multi-function handling system for use with a fiber optic cable reel at an installation site includes a base body and a roller assembly connected to the base body to support the fiber optic cable reel of the base body. The base body includes a connection interface for engaging with pallet handling equipment to move the handling system around the installation site. The roller assembly includes a plurality of rollers configured to allow the fiber optic cable reel to rotate relative to the base body to payoff a length of fiber optic cable on the fiber optic cable reel for installation at the installation site. A method of handling a fiber optic cable reel at an installation site is also disclosed.

A bobbin for winding optical fiber includes: a body around which an optical fiber is wound; a flange that extends in a radial direction from the body; and a seal that is bonded to an axially outer side surface of the flange. The flange has a void penetrating the flange. A part of the seal covers at least a part of the void. At least a part of a portion of the seal is non-adhesive. The portion covers the void.
