The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance.

I/O connector refers to the data transmission process that occurs between all operations, programs, or devices and a computer.

Connector, also known as Connector. Also known as connectors, plugs, and sockets. Generally refers to electrical connectors. A device that connects two active components and transmits current or signals.

Connector is a medium that connects two or more objects together. Connectors can be hardware, such as sockets, phone sockets, and so on that we see in our daily lives.

The military connector standards mainly include MIL-DTL-38999, MIL-DTL-5015, MIL-DTL-26482, MIL-DTL-83513, and IEC 61984.

Impedance is the total opposition a cable offers to alternating current. It includes both resistance and reactance and is generally expressed in Ohms.

As signals travel, they become weaker. This is as true with sounds traveling through air as it is with electrical signals traveling through wires. Attenuation is usually represented as a loss of decibels (dB). Other factors in the construction of cables make higher frequencies attenuate greater ("high frequency attenuation"). Cables, as listed in the Belden catalogs, intended for carrying signals, will show a list of frequencies and the loss at that frequency per standard length (100 ft. or 100 m) so that the performance of similar cables can be compared.

A dielectric material is used as the insulation material in cable products. Typical dielectric materials are polyolefin (PE or PP) and Teflon. PVC is normally not referred to as a dielectric material

Capacitance is the ability to store a charge. In cables, especially in digital applications, capacitance is a bad thing. Higher capacitance reduces overall cable run length and degrades the original signal.

Resistance in DC circuits is the opposition a cable offers to current, measured in ohms. In AC circuits, resistance is the real component of impedance.
