Abstract: Power distribution busses and methods are disclosed that provide flexible protection and alarming capabilities. Various embodiments provide interchangeability of fuses and circuit breakers within the same power distribution bus configuration. These various embodiments also provide discrete alarming for fused lines, discrete alarming for lines with circuit breakers, combined alarming for lines having mixed forms of protection, and/or selectable alarming such as combined versus discrete in relation to employing all fused lines, employing all circuit breaker protected lines, or employing mixed line protection.

Abstract: A power distribution panel with a chassis defining an interior with a first opening and a second opposing opening. The panel including a module with a bottom, a first face and a second face, and including a power input terminal, a plurality of power output terminals, and an electrical circuit connecting each power output terminal to the power input terminal, each circuit including a circuit protection device. The power input terminal, the power output terminals and the circuit protection devices are mounted to one of the first or second faces. The module is configured to be received through the first opening and removably mounted within the interior so that the power input terminal, the power output terminals and the circuit protection devices are accessible through one of the first and second openings when the module is mounted within the chassis. A module including power distribution components and circuitry adapted to be removably mounted within a power distribution panel chassis.

Abstract: A testing device for testing resistors of a telecommunications component, the testing device having a control system and an automatic test mechanism. The control system controls a test sequence performed by the automatic test mechanism. The testing device is programmed with a variety of selectable test sequences to automatically test and determine the resistive value and each individual resistor in a variety of telecommunication component arrangements.

Abstract: A method and apparatus are disclosed that permit multi-directional fiber optic connections to a device. The multi-directional aspect of the fiber optic connections permit the connections to be aligned closely with the direction of travel of the fiber optic cables that interface with the device. Closely aligning the fiber optic connections on the device with the fiber optic cables' direction of travel maximizes the bend radius of the fiber optic cable near the point of connection or eliminates the bend altogether and reduces the likelihood of a broken fiber or signal attenuation.

Abstract: A power supply is filtered while the amount of in-rush current required by the capacitive charging of the filter is limited. A resistor may be placed in parallel with a relay where the parallel combination is in series with the filtering capacitor. The relay is open upon applying power to the filter and remains open while the capacitor at least partially charges to cause charging current to pass through the resistor and thereby limit in-rush current. The relay is closed thereafter to provide a short circuit around the resistor and thereby unrestrict filtering by the capacitor. Alternatively, a common mode choke is disposed between a capacitor across input nodes and a capacitor across output nodes, whereby the size of the capacitors may be reduced to limit the in-rush current due to the common mode choke. The power supply filter may be included as part of a power distribution panel.
