摘要： A system and method for improving the efficiency and effectiveness of installing and pulling microducts through subterranean pathways is provided. The system includes a device that is placed over at least one microduct and secured through tapered screws that enter through the end cap of the body of the device and into at least one microduct. The tapered screw both expands the microduct, pressing it against the inner wall of the body and guide rod, as well as securing the microduct to the cap end of the body. Securing the microducts against seal provides further protection from water, debris, and other contaminants, and the expansion of the microducts provides friction and adherence to the body, aiding in keeping microducts in place. The device further includes a pulling apparatus connected to the device body, allowing it to be connected to a pulling mechanism for installation of the microducts.

摘要： A splice tray (100) to hold a splice holder device (180) configured hold both a mechanical splice and a fusion splice, each having a different shape. A splice holder device (180) includes a first splice channel and second splice channel. Each splice channel includes one or more flexible arms spaced along a length of the splice channel to provide a resistance against a housing of the splice. Also, each channel includes one or more base supports and one or more upper stops. The flexible arms extend from a channel wall at an angle to provide force components in orthogonal directions.

摘要： A torpedo is provided for use in pulling an optical communications device through ducts, vents, pipes, and the like. The torpedo has at least one mating feature formed thereon that mates with at least one mating feature formed on a boot of an optical fiber cable when the torpedo is attached to the boot. The mating feature formed on the torpedo is typically a key and the mating feature formed on the boot is typically a keyway having a shape that is complementary to the shape of the key. The mating of the key and keyway eliminate the need to use a clamping force to ensure that the grip between the torpedo and the cable will not be lost or compromised when the torpedo is being pulled. The boot of the optical fiber cable may be a standard boot of a standard optical fiber cable, and therefore does not need to be a specialized boot designed specifically for the purpose of attaching to a torpedo. The boot of the optical fiber cable is attached in the normal manner to the strain relief device of the optical fiber cable. Consequently, pulling forces that are exerted by the torpedo on the boot are translated through the boot into the strain relief device of the cable, thereby preventing forces from being exerted on the cable that could possibly damage it.
摘要翻译：提供了用于通过管道，通风口，管道等拉动光通信设备的鱼雷。鱼雷具有形成在其上的至少一个配合特征，当鱼雷附接到靴子时，其与形成在光纤缆线的靴子上的至少一个匹配特征配合。形成在鱼雷上的配合特征通常是钥匙，并且形成在靴子上的配合特征通常是具有与钥匙形状互补的形状的键槽。钥匙和键槽的配合消除了使用夹紧力的需要，以确保鱼雷与电缆之间的握柄在鱼雷被拉动时不会丢失或损坏。光纤电缆的引导可以是标准光纤电缆的标准引导件，因此不需要是为了附接到鱼雷而专门设计的专用引导件。光纤电缆的引导件以正常方式连接到光纤电缆的应变消除装置。因此，由鱼雷施加在靴子上的拉力通过靴子平移到绳索的应变消除装置中，从而防止力被施加在可能损坏绳索的绳索上。

摘要： A hauling shroud, a cable termination and methods of hauling a fibre optic cable with a pre-connected optic termination along a conduit. The hauling shroud protects the optic termination when being hauled along the conduit. The hauling shroud includes a first housing member and a second housing member such that the first housing member and the second housing member can be joined together to enclose the optic termination. At least one anchoring member is used, for example, connecting pins, such that at least one strengthening element of the fibre optic cable engages with the anchoring member inside an internal cavity formed within the hauling shroud. Alternatively, at least two strengthening elements of the fibre optic cable are attached together to form a loop which engages with the at least one anchoring member, e.g., the connecting pins. This prevents any hauling forces from being applied to the optic termination.

摘要： A method for installing a tubular cable-duct around a cable buried in the ground includes steps of freeing a portion of the buried cable from the ground in a forward longitudinal direction of the cable, starting from a free end of the buried cable, and advancing a foremost end of the cable-duct and subsequent portions of the cable-duct in the forward longitudinal direction of the cable over the portion of the cable freed from ground, starting from the free end of the cable. The advancing step includes the sub-steps of exerting pulling forces on the cable with a pulling device engaging the free end of the buried cable in a direction which is substantially opposed to the forward longitudinal direction of the cable, and exerting pushing forces with a pushing device engaging the cable-duct in a direction which is substantially opposed to the direction in which the pulling forces are exerted. An apparatus for installing the tubular cable-duct around a cable buried in the ground includes a winch provided with a winching wire having a coupling unit for providing a tension-proof coupling to a free end of the buried cable, a clamp which clamps an end of the cable-duct, a feed-unit which is coupleable to the end of the cable-duct for feeding a fluid to the cable-duct, and a displaceable support on which the winch, the clamp and the feed-unit are arranged in a mutually fixed position with respect to one another.

摘要： A plug may be deployed within a pipeline along with a fluid. The plug is coupled to a fiber optic line dispensed from fiber optic dispenser located outside or within the pipeline. The plug may transmit a signal via the fiber optic line that is indicative of the location of the plug within the pipeline. The signal may comprise light pulses associated with the traversal of a pipeline joint by the plug. The location may allow the plug to be reclaimed efficiently and economically should the plug become lodged within the pipeline. The plug may communicate other measurement information via the fiber optic line and this information may be used to adjust operational parameters associated with the pipeline.
