EZ-RJ45 design allows the wires to pass through the connector so the twists in each pair can be pulled closer to the contacts than conventional plugs. Maintaining the twists to the point of termination significantly decreases crosstalk and markedly increases performance. Substantially improve noise immunity at all frequencies, especially above 30 MHz when cable balance starts to significantly degrade. Category 6 performance per EIA/TIA B.2. FCC compliant, UL rated. RoHS compliant Max Cable OD: 6.60mm (0.260"), Max Insulated wire OD: 1.041mm (0.041") For solid round or stranded wire cables
