Bob Smith terminals, also known as Bob Smith terminal networks, are a technology used in Ethernet ports. This technology improves the performance of Ethernet interfaces by using resistors and capacitors to provide common-mode impedance matching. This helps reduce electromagnetic interference (EMI) and improves signal integrity. The "Bob Smith" technique uses a 75 Ohm resistor for a common mode impedance match at each signal pair, collectively connected via a 1000pF capacitor to the chassis ground. The resistors are typically placed in series with each differential signal line, and the capacitor is used for common-mode noise filtering. The purpose of this termination technique is to match the common-mode impedance of the transmission line, which helps minimize reflections and maintain signal integrity.
