Fiber optic cable assembly
A cable assembly includes a distribution cable, a tether cable, and a network access point (NAP) assembly having a cavity defined therein. The distribution cable includes optical fibers and the tether cable includes an optical fiber. The optical fiber of the tether cable is tightly constrained within the tether cable and portion thereof extends from the tether cable into the cavity of the NAP assembly and is spliced to a portion of one of the optical fibers of the distribution cable extending into the cavity of the NAP assembly from a side of the distribution cable. The splice is positioned in the cavity. Tight constraint of the optical fiber of the tether cable within the tether cable limits transmission of fiber movement to the portion of the optical fiber of the tether cable extending into the cavity of the NAP assembly, thereby protecting the splice.
Bundled cable assembly
A bundled cable assembly comprises groups of jumpers arranged to define a main section and terminal sections that each extend from the main section. The main section includes a plurality of tap locations at spaced apart locations along a length of the main section. At least some of the jumpers are bundled together in the main section between the tap locations. The terminal sections each extend from one of the tap locations. Each of the jumpers includes a first jumper end in one of the terminal sections and a second jumper end in another of the terminal sections. The groups of jumpers are arranged such that each of the terminal sections comprises the first jumper ends the jumpers from a respective group of the groups of jumpers and at least one second jumper end from each of the other groups of jumpers.
Terminal formed by sequentially assembled modules
A terminal includes modules adapted to be sequentially assembled together in a serial chain to build the terminal. At least some of the modules each include a module housing, a ruggedized optical output port provided on the module housing, a plug and play input connection location, a plug and play expansion connection location provided on the module housing, and an asymmetric power splitter within the module housing for splitting optical power from the plug and play input location asymmetrically between the ruggedized optical output port and the plug and play expansion connection location. The plug and play input connection locations and the plug and play expansion connection locations of adjacent modules in the serial chain are adapted to mate with respect to one another.
FIBER OPTIC CABLE ASSEMBLY FOR AN EQUIPMENT RACK AND METHOD OF USING SAME
A fiber optic cable assembly includes a fiber optic cable and a plurality of distribution housings along its length. The distribution housings include a tubular portion with a first passageway that receives optical fibers of the fiber optic cable and a branch portion with a second passageway. The second passageway intersects the first passageway and receives a subset of optical fibers that define tap cables branching away from the main fiber optic cable. The distribution housing includes one or more bend limiters adjacent the intersection between the passageways to limit bending of the tap cables. The distribution housings may include movement restrictors to limit movement of the distribution housings relative to the fiber optic cable. An equipment rack having such a fiber optic cable assembly is disclosed. A method of using the fiber optic cable assembly in an equipment rack to provide a plug-and-play capability is also disclosed.
Optical fiber connector
An optical fiber connector and method for assembly and use are disclosed. The optical fiber connector is configured to have a small footprint so that the connector may be pushable or pullable through a conduit if use of a conduit may be needed. The connector may include a first number of connector components configured to fit through a conduit, and a second number of connector components that are configured to be installed to the first components, for example, after the connector is pushed or pulled through a conduit.
Fiber optic cable assembly
A fiber optic cable assembly includes a distribution cable and a tether cable. The distribution cable includes a jacket having a generally flat profile such that the periphery of the distribution cable, when viewed in cross-section, includes two major surfaces of the jacket that are generally flat and are connected by arcuate end surfaces of the jacket. The jacket defines a cavity therein. Further, the distribution cable includes strength members embedded in the jacket and positioned on opposing sides of the cavity. The distribution cable includes a plurality of optical fibers extending through the cavity. The tether cable includes an optical fiber that is fusion spliced to one of the optical fibers of the distribution cable by way of an opening in a side of the jacket of the distribution cable.

Optical fibers deployment in the last mile
A method for connecting a number of users with at least one signal bearing optical fiber contained in an optical cable. The method includes: a) interrupting the signal bearing optical fiber at a first branch point, obtaining a first optical fiber segment upstream of the branch point and a second optical fiber segment downstream of the branch point; b) providing an optical splitter at the branch point, the optical splitter including an input and two outputs; c) coupling the first optical fiber segment with the input of the optical splitter; d) coupling a first output of the optical splitter with a first user; e) coupling a second output of the optical splitter with a downstream optical fiber segment of an interrupted optical fiber contained in the optical cable; and f) coupling the downstream optical fiber segment with at least one further user at a further branch point downstream the first branch point.
Mid-span drop cable clamp and method
A mid-span clamp includes an elongate base that defines a cable channel on a top side. The clamp includes a first pressure block connected to the base by a first control arm. The first pressure block includes a clamping surface and a top surface. The top surface includes a cleat. The clamp includes a second pressure block connected to the base by a second control arm. The second pressure block also includes a clamping surface and a top surface. The top surface includes a cleat. The clamp has an open position and a closed position. In the open position, a cable passageway is defined between the clamping surfaces of the first and second pressure blocks and the cable channel of the base. In the closed position, the clamping surfaces of the first and second pressure blocks close the cable passageway. The clamp is biased in the closed position.
