Hello Network Engineers,
I am a noob in the networking world. I am hoping to one day be able to answer questions such as the one I am posting and share as much as I learn with the rest of the community as I gain experience and knowledge. I am trying to find out if there is a piece of testing equipment that can test end to end Twinax cables both active (built in electronics) and passive. If there is no equipment or tester is there a procedure, I or anyone can use on a cisco device via the tdr (time domain reflectometry) command in various devices to test this. I have seen in some places where a site will setup a test environment that is up and functional, but no critical data is running through it. They will take a suspected bad cable and watch the whether the connection drops and returns. I am curious as to how these are quality tested. Is there a special software, hardware, or both needed? The primary reason is to potentially test this when we are installing new equipment and at new or older sites.
