[f-nsp] 10G-XFP-LR optics used on short links

[Eric Helm]

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.

Thanks,
