RJ45 Connector Circular Sealed Network Connector Factory

RJ45 connector performance index:

The performance indicators of RJ45 also include attenuation, near-end crosstalk, insertion loss, return loss and far-end crosstalk. Technical description of RJ45 performance: When the contact resistance is 2.5mΩ, the insulation resistance is 1000mΩ, and the electric strength is DC1000V (AC700V), there is no breakdown and arcing in one minute; 0.4mm ~ 0.6mm; the plug and socket can be repeatedly inserted and pulled out not less than 750 times; the 8-wire contact pin is plated with gold 509 (inch).

Among these performance index requirements, crosstalk is an important factor to be considered in the design. In order to make the entire link have better transmission performance, crosstalk cancellation technology is often used in the socket. The crosstalk cancellation technology can produce the same size as the interference introduced from the plug. , crosstalk signals with opposite polarities to cancel crosstalk. If the crosstalk interference introduced by the modular plug is indicated by "++++", the opposite crosstalk generated by the socket is indicated by "----". When the magnitudes of the two crosstalk signals are equal and the polarities are opposite, the magnitude of the total coupled crosstalk interference signal is zero
