Upcoming Events

Trade Shows

IWCS: October 3-4, 2016- OptEM will be exhibiting in booth 320 at the IWCS Conference/International Cable Connectivity Symposium in Providence, RI, USA. The IWCS presents the latest technologies in new and original wire and cable product design, materials, applications, processes and trends. OptEM will demonstrateOptEM Cable Designer, a cable design software tool customized to design, analyze and model electrical and propagation parameters for all types of copper cables.

Paper Presentations

OptEM will present a paper entitled "NEXT Between Screened Twisted Pairs" at the IWCS in October 2016 in Providence, RI, USA. The paper presentation details are as follows:

Paper Name - NEXT Between Screened Twisted Pairs

Date - Tuesday, October 4, 2016

Time - 8:00 AM to 11:50 AM

Session - Session 5 Copper Cables - Measurements & Modeling

Abstract - A mechanism of coupling between different lay lengths individually screened in Aluminum foil pairs (FTP) is discussed in the paper. Following a series of simulations and measurements the author found that there are distinct frequency points with high near end crosstalk (NEXT). It is established that the high coupling is caused by harmonic repetition patterns in mutual inductance of the pairs. It is shown that the optimal screen thickness is not only dependent on the transmission spectrum but also on the design parameters like pair lay lengths, wire dimensions and overall cable length. The paper suggests an analytical formula for the coupling parameters which helps investigate the impact of lay length, attenuation and cable length on the peak crosstalk levels between the pairs and also helps in optimizing screen thickness.

Awards

Best Technical Paper Award

On May 5, 2014 Dr. Juliusz Poltz, the president and co-founder of OptEM, was awarded the Urbain J. H. Malo Memorial award by the Wire Association International (WAI) for the best 2013 technical paper in the Electrical Division. The paper is entitled "Optimizing Shielded Pair Manufacturing" and was originally presented at the Interwire Trade Exposition, 83rd WAI Annual Convention, in April 2013 in Atlanta, GA. The paper examines a method for estimating the expected tolerance of cable propagation properties based on available manufacturing tolerances and calculated sensitivities. The work establishes that the twinax cable insulation diameter and copper/skin eccentricity are responsible for attenuation tolerance, whereas copper and skin diameters are responsible for characteristic impedance tolerance. This best paper (electrical division) award was presented to Dr. Poltz during the WAI annual meeting held at the WAI Operations Summit & Wire Expo in May 2014 in Indianapolis, IN.

Exhibitor Recognition Award
OptEM Exhibitor Recognition at the DAC

In June 2013 OptEM was presented with an Exhibitor Recognition Award for 20 or More Years of Participation at the Design Automation Conference. TheDACis the premier conference and tradeshow covering the latest trends in electronic design and design automation (EDA). The 2013 DAC celebrated 50 years of innovation in EDA with a special banquet and ceremonial events at the conference in Austin, TX, USA. OptEM was pleased to receive this award and participate in this special event.

Past Events

IWCS October 2015
OptEM at the IWCS

OptEM showcasedOptEM Cable Designer, a cable design software tool customized to design, analyze and model electrical and propagation parameters for all types of copper cables, and presented a technical paper entitled "Impact of Quad Cable Manufacturing Tolerances on NEXT" at the International Wire & Cable Symposium in Atlanta, GA, USA. In quad cables NEXT is affected by manufacturing parameters that influence quad symmetry. The paper summarizes that with harmonic distribution of eccentricities the quad experiences NEXT resonance similar to UTP cables. Measured and simulated NEXT results match if simulation includes a combination of continuous and spiral eccentricities. For more information please review the paperabstract.
