Embodiment Construction

[0058]FIG. 1 shows an alien crosstalk test system 40 of the present invention, which uses a pair of alien crosstalk measurement units 50 and N pairs of alien crosstalk test signal units 60 , where N≧1. In general, the crosstalk measurement unit 50 is structurally configured to be connected to opposite ends of the victim cable 30 having M wire pairs, and each pair of alien crosstalk test signal units 60 is structurally configured to be connected to the opposite end of the victim cable 30 having M wire pairs. The opposite end of the interference cable 31, where M≥1. Each pair of crosstalk generators 60 is further structurally configured to generate an alien crosstalk test signal at one end of the connected disturbance cable 31 and terminate the alien crosstalk test signal at the other end of the disturbance cable 31 . The crosstalk measurement unit 50 is further structurally configured to measure the alien crosstalk signal at one end of the victim cable 30 and terminate the alie...

Abstract

Disclosed is a multi-jack cable adapter for multi-cable testing and alien cross-talk cable testing. The cable testing system employs the cable tester and the multi-jack cable adapter, and the adapter includes a switch matrix and a switch controller. In operation, the switch matrix and the cable tester build a plurality of signal channels with a plurality of cables for telephonic communication between the cable tester and a plurality of cables, and the switch matrix and the switch controller process the telephonic communication with the cable tester according to the command control switch matrix of the cable tester to switch between the active state and the null state on each signal channel.

Description

technical field [0001] The present invention relates to multi-jack cable adapters for multi-cable testing and alien cross-talk cable testing. Background technique [0002] Multi-cable testing typically involves an operator connecting the local end of the cable to a cable tester at the local location and then connecting the remote end of the cable to the cable tester at the remote location. When testing a cable at a local location, the operator disconnects the local end of the cable from the local cable tester and then disconnects the remote end of the cable from the remote cable tester, thereby aiding in testing the other cable. test. Depending on the distance between the local and remote sites and the number of cables being tested, this way of performing multi-cable testing may take unacceptable time. [0003] In addition, alien crosstalk between cables reduces the operating bandwidth of the cable channel because the overall signal-to-noise ratio decreases due to increase...
