Hallo Eric,
aufgrund deiner geschilderten Exprtise habe ich eine Frage zum Verständnis dieses Zitats:
“What is a Layer 1 switch?
A physical layer switch, or Layer 1(L1) switch, operates at the physical layer of the OSI (Open System Interconnection) model.
The easiest way to think of a Layer 1 switch is an electronic, programmable patch panel. It simply establishes the physical connection between ports.
The connection is established using software commands and thus, allows test topologies to be automatically or remotely configured.
A Layer 1 switch does not read, manipulate or use packet/frame headers to route the data. Layer 1 switches are fully transparent to the data and typically have very low latency. Completely transparent connections between ports are important in testing environments as this allows the tests to be as accurate as if there were a patch cord between the devices.”
Was bedeutet “volltransparent”?
Heißt das, daß auch alle Störungen des Senders mitübertragen werden?
Gleichtaktstörungen wohl eher nicht, aber vielleicht noch andere?
Danke und viele Grüße
Roland
