Overview
Dual-ended copper testing with an UltraFED IIB can isolate customer-affecting fault conditions that otherwise go undetected during turn-up and installation or routine copper troubleshooting. The UltraFED IIB connects to the far end of copper pairs under test while a single technician controls it remotely using the HST-3000.
Benefits
- Reduces back-and-forth drive time to change line conditions Provides line terminations and remote test capabilities
- Built for the future — isolates crosstalk for VDSL2/ADSL2+ bonded pairs
- Thru-mode operation takes customers out of service only when necessary
- Greatly simplifies fault isolation and identification for less-skilled technicians
- OneCheck™ diagnostics identify faults up to three times faster
Applications
- Second-pair operation to accurately assess the effects of near-end crosstalk (NEXT) and far-end crosstalk (FEXT)
- Remotely, from the VIAVI HST-3000, provide strap (short), open, drop battery, transmit tones and trace tones
- View pair endings with TDR Helper, enabled on the HST-3000, which provides alternating short and open to the pair
- OneCheck Copper Test Suite provides simple diagnostic tests that isolate typical faults a technician encounters every day
- OneCheck Copper for DSL – Determines overall pair(s) health over the DSL technology provided with thresholds and filters set by technology
- OneCheck Series Fault – Check for series fault presence, typically from splice failures
- OneCheck Bridged Tap – Determines bridged tap (lateral) existence on the pair with distance to and length of tap
- OneCheck TrueLength – Provides actual pair length by correlating capacitive, resistive and TDR loop measurements
- OneCheck RFL Pretest – Indicates whether a resistive fault was found and identifies to run next to precision locate it
- OneCheck Kick Test – Quick copper-check to assess the pair’s health prior to final test
- OneCheck Shield Test – Determines resistance from the HST-3000 to the UltraFED IIB
