Yet more Soliton stuff, and French too! But Frank is absolutely correct-this is a Last Mile thread, not a long haul thread, although some technologies which begin in the long haul filter down to the access eventually, right?

ALGETY TELECOM DEVELOPS UNIQUE SOLITON DWDM
Algety Telecom, a start-up based in Lannion, France, announced plans for the first commercial soliton DWDM transmission system for long-haul networking. The soliton phenomenon describes how waves of longer frequency travel faster than the waves of shorter frequency. After a collision between a solitary wave of high amplitude (fast) and another of lower amplitude (slow), the two waves come back to their initial shape. The solitary waves returning to their original shape after a collision are called solitons. Algety said a soliton light wave effect could be leveraged in fiber transmissions to create very high speeds per transmitted channel. Speeds up to 100 Gbps have been demonstrated in the laboratory using solitons. Algety's soliton transmission system will be combined with DWDM to enable terabit transmission capacities over distances of 1,000 km. Prototypes are expected by the end of the year. Algety is the brainchild of a team of engineers out of CNET, the R&D arm of France Telecom. The company has raised $7.4 million in first round funding from Banexi Venture Partners, Crescendo Ventures, Newbury Ventures and Technocom Ventures, as well as French governmental agencies including ANVAR (Agence National de l'Innovation).
