Telecom Italia,Latin Telecoms Invest $800M In Optic Proj
Dow Jones Newswires

MILAN -- Telecom Italia SpA (TI) said Thursday that it is forming a new company called Latin America Nautilus with Telecom Argentina (TEO), Entel Bolivia and Entel Cile.

Latin America Nautilus will have initial capital of $120 million, with investment totaling $800 million. TI will hold 70% of the venture and the remaining companies will each hold 10%.

Latin America Nautilus will run a ringed submarine and grounded fiber optic network of about 30,000 kilometers, TI said. The network will connect the most important South American capital cities with large cities in Central and North America, the Italian company said.

TI said it intends to involve Brasil Telecom (BRP) in the project as well. It declined to be more specific.

The companies jointly plan to obtain a 20% share of Latin America's Internet connection and data transmission market, TI said.

TI is constructing a similar underwater fiber optic network encompassing Italy, Israel, Greece, Turkey and Egypt.

Corning and Siemens demo 40Gbps systems:

The demonstration will transmit eight channels of simulated live traffic, error free, at 40 Gb/s per channel over 4 x 100 km spans (400km) of LEAF fiber. By integrating Siemens' 40 Gb/s systems and DWDM terminal TransXpress Infinity with Corning's LEAF fiber, PureGain EDFA and Raman amplifiers, and PureForm DCM Modules for LEAF fiber, both companies have achieved the capability to manage the power, noise, dispersion and non-linear effects at 40 Gb/s transmission rates. The large effective area of LEAF fiber reduces peak light intensity in the core of the fiber and allows more power to be pumped into the network while reducing the non-linear effects that can degrade system performance. This feature also allows the best balance of Raman pump power level and EDFA output power and provides an optimal signal-to-noise ratio (SNR).
