IsoTek EVO3 Optimum

At the Optimum’s core are three silver-plated Ohno Continuous Cast (OCC) copper conductors, with each conductor strand being of a square configuration for tighter bunching. The OCC offers a vastly superior level of purity with outstanding electrical conductivity, improved flexibility, resistance to fatigue and corrosion.

 A high-quality FEP provides a very low dielectric constant over a wide frequency range. The three conductors are given a slight rotational twist to aid RFI and EMI rejection and are then surrounded by a cotton filler which gives internal strength and reduces microphony.  The whole construction is enclosed in a Mylar wrap to provide an additional dielectric buffer, before applying an active OFC shield for maximum rejection of high-frequency interference. A durable PVC outer jacket gives a high degree of flexibility and mechanical strength.
