EAD-socket
From Wikipedia, the free encyclopedia
EAD is an abbreviation for German Ethernet-Anschlussdose. The EAD standard defines wall mounted ethernet connection outlets that enjoy a higher reliability than standard T-connectors.
EAD outlets have been developed from TAE connectors for telephony applications but they are intended for connecting coaxial network cables like 10BASE2. A different mechanical encoding (Type E) prevents mix-up with phone plugs.
EAD cables are duplex connections replacing two thin-wire cables. The contacts of an EAD outlet are closed if no connector is plugged in. When a cable is plugged in, the normally closed contacts in the socket are opened so that signals pass through the loop cable.
