Abstract: A system for detecting a location of optical energy leakage from optical fibers, including a portable imaging device for generating a visible image of one or more optical fibers within a field of view of the portable imaging device, an optical energy detector assembly associated with the portable imaging device and configured to detect a location of optical energy leakage from an optical fiber within the field of view of the portable imaging device, and a processor associated with the imaging device and the optical energy detector assembly for overlaying a computer generated representation of the detected location of optical energy leakage from an optical fiber within the field of view of the portable imaging device over a visible image of the plurality of optical fibers generated by the portable imaging device to create a composite image.

Abstract: There is provided techniques for improved visualization of wireless devices in a communication network. The techniques include receiving, via an identification device, real-time display data, determining, via the identification device, a location of a network device and displaying, via a display of the identification device, the real-time display data and an indication of the location of the network device relative to the real-time display data.

Abstract: An instrument is disclosed that is capable of detecting and graphically displaying channel usage and the number of access points operating on each channel of interest. By using a module that counts the number of elapsed clock cycles, the total cumulative duration of detected frames, and the number of channel in-use cycles, the instrument can determine the percentage of time a channel is in use, the percentage of time of IEEE 802.11 usage on a channel, and the percentage of time of non-IEEE 802.11 usage on a channel. Further, channels are scanned for access point activity using a scanning algorithm that interleaves scanning channels at a first duration longer than the beacon interval and scanning channels at a second shorter duration.

Abstract: An instrument to measure crosstalk between conductor pairs is configured to transmit a signal at one pair and receive the signal at another pair. The spureous or parasitic crosstalk at the connectors is supressed using a vectorial substraction from the received signal.

Abstract: Apparatus to measure the crosstalk between pairs of conductors in a cable. The measurements are affected by the crosstalk inherent to the connectors that are part of the apparatus. The improvement consists of adding a compensating signal which equals that from the connector crosstalk in magnitude but has opposite sign.
