Scope

Alcatel propose to offer the following elements for an undersea Neutrino telescope in a turnkey approach:-Submarine cable (OALC-4, power+fibers);-Cable Termination Assembly (CTA);-Node/Jointing Box (different solutions foreseen):

- Single node solution (8 x10/100/1000 Mbit/s, 9 KW)

(Oil & Gas Solution)- Multiple nodes WDM solution (2 x GigE per node, 9 KW per

node)

(NEPTUNE Canada Solution)
