While I like those the most because data centre x-connects will generally be under 2km long, experience is showing that operators are carrying their "LR4" habit into 100G-LR1 world :-).
Distance is a bogus metric, most of the time it's about the loss. See shrinking link budget for 10km as you go from 1 to 10 to 100G.
100G-LR1 plugs are about 12% more expensive than 100G-FR1, on average, but it seems old habits die hard :-).
Having an extra dB or two when equinix are messing in the MMR is worth it. Also one less type to carry spares for. brandon
