摘要:
The invention relates to a means of cable strain relief (1) comprising a crimping sleeve (3) for the mechanical operative connection of a cable (5) to a crimping neck (2), wherein the crimping sleeve (3) is used in the crimped state for clamping a textile braid (7) of the cable (5) intended for stain relief between the crimping sleeve (3) and the crimping neck (2). At its cable-side end, the crimping sleeve (3) comprises a deformable plastic sleeve (4) that produces a mechanical operative connection in the crimped state between an exterior jacket (6) of the cable (5) and the crimping sleeve (3).

Cable assemblies having a connector (100) with a stable fiber length within the connector and methods for making the same are disclosed. In one embodiment, a filling material (22) is disposed in the passage-way of a fiber optic cable (30) near a first end (26) where the connector is attached for inhibiting the optical fiber from movement adjacent to the first end of the cable. The filling material may be placed into fiber optic cable using any suitable method such as injecting into the end of the cable or forming a window in the cable and inserting the filling material into the window.

Fiber optic cable mounting adapters and related fiber optic cable assemblies and methods for attaching an external mounting device to the fiber optic cable are disclosed. The fiber optic mounting adapters (12) can be configured to be secured to a portion of a fiber optic cable. The fiber optic mounting adapters can also be configured to be secured to external mounting devices compatible to be secured to fiber optic equipment, to secure the fiber optic mounting adapter, and in turn the fiber optic cable, to the fiber optic equipment. Securing a portion of a fiber optic cable can reduce or prevent bending strain from being propagated along the fiber optic cable. Undesired bending strain of a fiber optic cable can cause undesired optical attenuation. Bending strain can also risk damaging optical fibers, such as furcated legs, exposed from the end portion of the fiber optic cable.

Fiber optic cable furcation methods and assemblies are disclosed, wherein the method includes removing an end portion of the cable outer jacket (41) from the fiber optic cable to expose end portions of the micromodules (60E) contained within. The method also includes helically stranding the exposed micromodule end portions to form a stranded section (110) having a stranded configuration that includes at least three turns and that substantially immobilizes the optical fibers within their respective micromodules. The method also includes arranging a maintaining member on at least a portion of the stranded section to maintain the stranded configuration.
摘要:
A furcation tube (10) for an optical fiber cable comprising a plurality of channels (16a,16b) for receiving a plurality of optical fiber strands that allows for the breakout of multiple fiber groups without the need for marking individual fibers. For example, a 24 fiber cable can be broken out into two, 12-fiber groups within the same furcation tube for connectorization. This improves the sortabilility of the optical fiber strands and eliminates the extra bulk of using multiple furcation tubes. The furcation tube includes strength members (32) disposed therein for strain relief.
摘要:
A sealing and strain relief device having at least one sealing element is disclosed. The device is arranged in the manner of a sandwich between outer, plate-like bearing elements made from a relatively hard or rigid material and which is made from a relatively soft or elastic material. Slots are introduced both into the outer bearing elements and into the or each central sealing element in such a way that the slots run respectively next to one another and respectively one behind the other, in relation to the sandwich-like arrangement thereof, within the respective bearing element and within the respective sealing element. The strain relief elements are associated with at least one plate-like bearing element such that each data cable, which is sealed and is guided in the region of slots arranged one behind the other of the sandwich-like arrangement, can be restrained using a strain relief element.
