Even tough you don't need regeneration before 2000-4000 km if you are using Lucent optical DWDM system or Nortel's LH4000 DWDM system you still need an optical amplifier at each 100~130km. How will you bring power to does OAS (optical amplifier site) they generally need 60 AMP of power.
One way it to use underwater transoceanic amplifier systems (Alcatel, Tycom)
