A communications protocol is a system of digital message formats and rules for exchanging messages in or between computing systems and in telecommunications. A protocol may have a formal description. Protocols may include signaling, authentication, and error detection and correction capabilities. The first part of this document provides an overview of the most relevant parameters that determine whether a connector and/or a cable assembly can withstand a defined data protocol. The second part shows the performances of the Fischer MiniMax™ Series and the Fischer UltiMate™ Series cabled connectors according to Ethernet, USB and HDMI protocols.
