Abstract: Armored fiber optic assemblies and methods are disclosed that include a dielectric armor and at least one bend-resistant multimode optical fiber. The dielectric armor has an armor profile, thereby resembling conventional metal armored cable to the craft. The dielectric armor provides additional crush and impact resistance and the like for the optical fibers and/or fiber optic assembly therein. The dielectric armor is advantageous to the craft since it provides the desired mechanical performance without requiring the time and expense of grounding like conventional metal armored cables. Additionally, the armored fiber optic assemblies can have any suitable flame and/or smoke rating for meeting the requirements of the intended space. The use of at least one bend-resistant multimode optical fiber allows for improved bend performance for the armored fiber optic assemblies, allowing for tighter cable routing as compared to armored fiber optic assemblies having conventional multimode optical fiber.
Abstract: A fiber optic cable assembly including a fiber optic cable and a furcation body is disclosed. An attachment feature can be provided to mount the furcation body to a mounting surface of fiber optic equipment for securing a portion of the fiber optic cable assembly to the fiber optic equipment. The attachment feature may include an integrated anti-rotation feature to inhibit rotation of the furcation body with respect to a mounting surface. The anti-rotation feature is provided by one or more generally planar surfaces of the furcation body for abutting with at least one complementary planar mounting surface.

Abstract: Fiber optic cable assemblies having furcation bodies with features that are advantageous for manufacturing are disclosed along with methods of making the same. The furcation body include at least one anti-rotation feature for mounting the furcation body and a viewing portion and/or weep hole. The viewing portion is advantageous since it allows the observation during filling of the cavity with an epoxy, adhesive, or the like to strain relieve components of the fiber optic cable assembly within the furcation body. Simply stated, the viewing portion is translucent or clear for observing the filling of the furcation body and detecting if an air bubbles/air pockets are formed so that they can be reduced and/or eliminated. The furcation body may also have a weep hole for allowing air bubbles/air pockets to escape. Additionally, the furcation body of the fiber optic cable assembly may be secured within a clip or other suitable structure for mounting the same.

Abstract: Micromodule subunit cables are constructed to allow for ease of identification between optical fibers in differing groups of optical fibers. In one cable, a first group of fibers is located within a buffer tube core while a second group of fibers is located within the cable jacket, but outside of the core. The fibers in the first and second groups can accordingly use the same color coding sequence without requiring additional indicia such as stripes or binding.
Abstract: A clip for securing one or more fiber optic cable assemblies having respective furcation bodies is disclosed along with related assemblies. The clip includes one or more attachment features disposed on a bottom surface for mounting the clip. The bottom surface of the clip provides an anti-rotation feature for the clip and the fiber optic cable assembly by abutting with the complementary mounting surface. In one embodiment, the clip has a cover that attaches to a portion of the clip for securing a portion of the furcation plug within a cavity of the clip.
Abstract: An optical cable comprises a plurality of elongate members wherein at least one of the elongate members include at least one optical fiber surrounded by buffer tube. The buffer tube is made of a soft material having a tension at break of less than 7.5 MPa. The elongate members are disposed around a central element. A binder is wrapped around the plurality of elongate members. An outer jacket surrounds the plurality of elongate members.

Abstract: A connector housing for use with a communication network and management system thereof includes a housing having a plurality of berths each configured to receive an optical connector adapter unit. A housing electrical connector is associated with each berth and faces the front of the housing to engage an adapter unit electrical connector as the adapter unit is inserted into the berth. Guide elements guide and align the housing electrical connectors with the adapter unit connectors as the adapter units are inserted into the berth to allow blind mating of the housing electrical connectors and the adapter unit connectors. Electrical contacts from at least two housing electrical connectors are consolidated into a cable connector positioned adjacent the back of the housing.
