Hello, I'm working some XMR routers that only have 10G-XFP-LR optics
available. There is one short link connecting to XMR routers of around
3 meters. Should an attenuator be used on these links? I've looked at
the output of 'show optics' and the XFPs are operating within a normal
range. I'm concerned that some damage may occur to the XFPs in this
case.
LR was designed to work without attenuators.
Please don't fearmonger. We're talking run-off-the-mill standard optics
here so the saturation point for the receiver is far removed from the
damage point. The only damage that can occur is if you drop them or
cough into them.
