Thales launches technology prize for ideas from Scottish universities
News & Analysis  
9/1/2009   Post a comment
Thales UK has announced the launch of its second Thales Scottish Technology Prize. This year, the company is looking for creative and innovative ideas in the areas of data and image processing and their associated applications.

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
