R&D Environment for Cat.6 Connecting Hardware
Electrical Measurements
  The following electrical transmission parameters have been measured for all pairs or combination of pairs for the tested connecting hardware samples:
 
  • Return loss from 1 MHz - 250 MHz, measured from both sides of the connecting hardware
  • Attenuation from 1 MHz - 250 MHz
  • Pair-pair near end crosstalk from 1 MHz - 250 MHz, measured from both sides of the
    connecting hardware
  • Pair-pair far end crosstalk from 1 MHz - 250 MHz, measured for all 2×6 combinations of pairs
  • DC resistance
  • DC resistance unbalance
  • Current carrying capacity
  • Propagation delay from 1 MHz - 250 MHz
  • Delay skew from 1 MHz - 250 MHz
  • Coupling attenuation and EMC performance from 30 MHz - 1 GHz, recorded as both near and far end measurements
  • Common mode balance from 1 MHz - 250 MHz, measured as TCL from both sides of the connecting hardware
  • Transfer impedance from 1 MHz - 100 MHz
  • Insulation resistance
  • Voltage proof
   
  The following instruments were applied for the electrical measurements:
 
  • HP Network Analyzer, type 8753ES with Internal S-Parameter Test Set
  • BH Electronics Baluns, type 040-0093
  • 3P Baluns, type 3P-250-Cat6-C
  • 3P Balun, type 3P-600-Cat7
  • Rohde & Schwarz Absorbing Clamp, type MDS-21
  • HP Milliohmmeter, type 4338A
  • HP LCR Meter, type 4263A
  • HP High Resistance Meter, type 4339A
  • Danbridge Insulation Tester, type JP12A
Final Testing
  Telebox Industries Corp. has very extensive electrical high frequency testing of produced
connecting hardware, which is documented as either pass/fail result or with recording of tested
electrical parameters in the full specified frequency range. Failing components are offered to the
customer with documented performance data.

Frequency of testing depends on component type and experience, but no documented sampling
procedure is present at Telebox Industries Corp
.

The following data for final testing at Telebox Industries Corp. has been concluded by 3P:
 

Visual inspection: 100 %
Continuity (dc) testing: 100 %
Testing for Shorts: 100 %
Near End Crosstalk measurements: 10 % - 100 %
(most of the sampling is only recorded as fail/pass)
Insertion Loss, Return Loss and
Far End Crosstalk measurements:
Type testing
High Voltage testing and Insulation
Resistance Measurements:
Type testing
  Test results are stored in the quality department for three years.

The following instruments were applied at Telebox Industries Corp. for performing the ongoing
quality assurance testing:
  High Frequency Testing:
 
  • HP Network Analyzer, type 8753E
  • Agilent ENA Network Analyzer, type E5062A
  • BH Electronics Baluns, types 040-0092 and 040-0093
  • North Hills Baluns, type 0322 BFX
