All links will be local (<1ms RTT) except link to DE-CIX where we
taking 10G via 3rd party DWDM and RTT is around 4-5ms.

I think about ER as I have one node where fiber distance is around
24KM. LR optics will not handle this at all. In the past I saw LR20
(X2/XENPAK/XFP) optics - LR but with increased power budget to 20KM.
I'll check is it available at SFP+ form faction.

Thanks a lot,
