A hybrid cable for telecommunications systems is disclosed. The hybrid cable may include a plurality of fiber-optic cables and power cables extending within an armor member and an outer jacket in a main body portion of the hybrid cable, and extending outside of the armor member and the outer jacket in a termination portion of the hybrid cable. Shielded tube assemblies may be attached to the power cables in the termination portion to provide electrical shielding to the power cables in the termination portion of the hybrid cable. The shielded tube assemblies may be attached to the armor member to electrically ground the shielded tube assemblies. A method of constructing a hybrid cable is also disclosed.
摘要:
A tool for stripping off a jacket from tubes or cables is characterized by a bend adapted to an outer diameter of the duct or cable to be stripped, and a blade protruding from the bend to the interior of the bend. The invention provides a cost-effective, accurate and easily producible tool for stripping off a jacket from tubes or cables.

摘要:
Method and system of adjusting a first phase shift between a first data signal and a clock signal at a sending device. First and second test signals representing first and second test data, respectively, are transmitted to a receiving device. The test signals have respective phase shifts relative to the clock signal. An error detection code is calculated from first and second received data carried by the transmitted signals. The error detection code is transmitted from the receiving device to the sending device. An estimated first received data is calculated from the error detection code, wherein the estimated first received data are calculated under the assumption that the second received data are identical to the second test data. The first phase shift is adjusted on the basis of a comparison of the estimated first received data and the first test data.
摘要:
A method of contacting an electrical conductor (1) having a conducting core (2) covered partly by an insulating material (3), comprising installing a contacting device (10) in electrical contact with the conducting core in a position (4) where the conducting core is free from the insulating material. Said method further comprises a flexible element (5) comprising an electrically conducting material over the conducting core in said position prior to installing the contacting device, the flexible element comprising at least one adhesive portion (8) which adheres to the insulating material in a vicinity of said position and a non-adhesive portion (7) which contacts the conducting core.
摘要:
A signal converter circuit including an input circuit and an output circuit. The input circuit is configured to receive current mode logic signals and provide differential input signals based on the current mode logic signals. The output circuit is configured to receive the differential input signals and provide rail-to-rail output signals based on the differential input signals. The output circuit is configured to switch the rail-to-rail output signals in response to a common edge type in each of the differential input signals.
摘要:
Methods and apparatus for adjusting a phase difference between clock signals. A first clock signal at a memory controller is adjusted relative to a clock second signal at a memory device. In one embodiment, data is transferred to the memory device according to the first clock signal, which has a predetermined phase relationship with second clock signal. Data received at the memory device is sampled at the memory device according to the second clock signal. Analysis is done of the data on the memory controller and of the received data on the memory circuit. On the basis of the analysis, an adjustment may be made to the phase relationship.
