(network)technologies used by NSA for data collection

I see, thanks! However, this all requires at least some level of
Internet operator cooperation? For example if ISP in Northern Europe
owns a sub-marine cable between Finland and Sweden and they decide to
upgrade their legacy Nortel equipment with STM-64 line-card in both
ends of the cable to a Juniper T1600 core routers with 100GigE
line-cards, then it's not possible that intelligence agency equipment
supports this, is it?
In addition, how is the collected data transported for storing in
(NSA) datacenters and later analysis? I guess the data collection
actually has to be fairly selective simply because the amount of data
is so huge. For example take the large Internet Exchanges where
several Tbps of data are exchanged in peak hours each day.
