4 About Telebox 4 Core Competence   R&D Equipments   QC Equipments   Tooling Development   Automatic Machine Development       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       dc Resistance and Short Circuit Testing:   Microtest dc test equipment, type CT-8687 Microtest dc test equipment, type CT-8681 Wayne Kerr LCR Meter, type 4273 Chen Hwa Milliohmmeter, type 502AC Instek AC/DC Withstand Voltage / Insulation Tester, type GPI-735   5 Top R&D Equipment Coupling attenuation clamp Low frequency NWA for video system Salsa Plug Balun Test Head Assy + Direct Fixture AxTalk Analyzer 10G Programmable Mili-Ohm Meter Transfer Impedance Test GW Instek LCR Meter Wayne Kerr LCR Meter Microtest dc test equipment C3D Inkjet Rapid Prototyping (16 microns two ways) Video Measuring Microscope           Engineering Design 80% of the product competitiveness is determined by Research   Our team has grasped the key technologies in our industries. We take a macro view of the product system: understand different departments' characteristics and requirement, introduce the technology via our engineers and associates, and integrate products mix with efficiency. All efforts concentrate to develop the quality products with good function and the value within deadline to achieve competitiveness.       Design Development Process     5 Top © 2007 Telebox Industries Corp.
