TeraXion introduced its CS-CDE compact, low loss chromatic dispersion module that emulates tens of thousands of picoseconds per nanometer and extends its ClearSpectrum dispersion compensator family. The PS-TNL, an ITLA-based Tunable Narrow Linewidth laser, offers white noise suppression using a patented optical filtering technique. Finally, the PS-LS Laser Synthesizer, featuring a high-gain analog optical phase-lock loop (OPLL), is also a new element to the PureSpectrum specialized lasers portfolio.http://www.teraxion.com
