The sophisticated cable test instrument family of ELEKTRONIKA won the Innovation Prize of the Hungarian Innovation Found in 2002. The copper access network cables built during the last hundred years should be made suitable for the high speed data transfer due to the quick widespread of the Internet. To solve the problem suitable instruments are required. ELEKTRONIKA developed a family of four instruments for the test of access lines to be used for high speed Internet data transfer together with the original telephone service. EFL 10 Fault Locator Bridge (Deutsche Telekom type KMB 2002) ETDR 10 Reflectometer (Deutsche Telekom type TDR 2002) ELQ 2+ xDSL Line Qualifier

All the physical and electrical parameters of access lines can be measured by the three instruments. After automatic evaluation of test results the sufficiency of the tested line for a given DSL system is directly indicated. The measurement processes applied at the three cable tester instruments are considerable innovation result of the developer team of Elektronika. Main menu
