I want to confirm something.If the laser transmitter is disabled, when I go "disable port" on an Extreme 670V switch, loaded with Finisar 10G optics? I am trying to determine if we need to remove the fibres from the SFP+s before testing them with an OTDR. I suspect the answer is I need to remove them, which is what we are doing at the moment but it's very tedious with such a large site. However, I am told that an optic laser can damage the OTDR, so I am also interested in the question, in case I pull the wrong fibre at the far end but the correct port is disabled. I am hoping this won't damage the OTDR.
