摘要： A fiber optic cable (10) having a tube assembly (20) therein. Tube assembly (20) includes an optical fiber group (22) in a tube (21). Optical fiber group (22) comprises a medial optical fiber subgroup (23) and lateral optical fiber subgroups (24a,24b;25a,25b;26a,26b) adjacent thereto. Subgroups (24a,24b;25a,25b;26a,26b) define a step-like profile for maximizing optical fiber packing density of tube assembly (20) and/or defining a high fiber count cable (10). In an exemplary embodiment, fiber optic cable (10) can include strength assemblies (30) on opposing sides of tube assembly (20) for defining a preferential bend plane in fiber optic cable (10).

摘要： A fiber optic cable having strength assemblies (30) adjacent a tube having at least one optical fiber therein, at least one of the strength assemblies including a strength member for imparting crush resistance to the cable. The strength member is generally coupled to a first jacket, and may be surrounded by a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. The arrangement of the cable components and strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distributes the stress for preventing crush induced attenuation in the optical fibers.

摘要： A fiber optic cable having strength assemblies (30) adjacent a tube for imparting crush resistance to the cable, at least one of the strength assemblies including a strength member in contact with a tube having at least one optical fiber therein. The strength member is coupled to a first jacket, and may be surrounded a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. Tight coupling and minimized gaps between the cable components in strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distribute the stress for preventing crush induced attenuation in the optical fibers.

摘要： A system for monitoring an optical cable includes a cable having monitor fibers solely for monitoring cable status. The monitor fibers may be fibers selected from optical fibers having a higher mechanical sensitivity to mechanical stresses than other fibers in the cable, which may attenuate earlier than the other fibers in the event of cable degradation. The monitor fibers may be in communication with a transmitter and receiver, for transmitting and receiving a monitor signal. The receiver may be in communication with an alarm, the alarm being operative to send an alert signal when an increased attenuation is detected from the monitor signal, the increased attenuation being indicative of the status of the optical cable.

摘要： A ruggedized cable has an inner and an outer jacket. The cable also includes two layers of aramid strength elements for tensile strength. The cable can be pulled through various environments due to the jacketing and strength elements. The outer jacket and strength elements can be stripped away at a transition point, and secured at an entry point of a housing of an FDT, ONT, etc. The remaining inner cable element is then routed through the hardware housing and terminated.

摘要： A fiber optic cable includes a jacket, strength members, armor, and a tear feature. The jacket is formed from a first polymeric material and defines an exterior of the cable. The jacket further forms an interior cavity configured to support an optical fiber. The strength members are each surrounded by the jacket, with the cavity separating the strength members from one another. The armor extends above the cavity and at least partially above the strength members, and has greater tensile strength than the first polymeric material. The tear feature is located beneath the armor and is formed from a second polymeric material co-extrudable with the first polymeric material. The tear feature forms a discontinuity of material within the jacket. At least one of the second polymeric material and the interface between the first and second polymeric materials yields at a lesser tearing force than the first polymeric material.
