BEAVERTON, Ore. -- Tektronix, Inc., the world's leading manufacturer of oscilloscopes, today announced that the accurate, fast acquisition system of the Tektronix DPO72004B oscilloscope combined with OM4105 and OM4106 Coherent Lightwave Signal Analyzers from Optametra deliver unprecedented ability to visualize and measure coherent polarization multiplexed quadrature phase shift keying (PM-QPSK) signals in realtime.

Tektronix and Optametra will be providing a joint demonstration of the solution during the OFC/NFOEC conference March 23-25 in San Diego, Calif. To view the joint demonstration, please visit the Tektronix booth# 1543 or the Optametra booth# 1406. OFC/NFOEC is the world's leading global conference for optical communications and networking professionals.

Optical transmission rates above 10 Gb/s significantly increase signal distortion caused by fiber impairments. To solve this problem, the industry is turning to PM-QPSK paired with coherent detection. This complex modulation scheme gives carriers the ability to grow data rates significantly over their existing fiber infrastructure.

The challenges of testing PM-QPSK are considerable, involving a complex optical modulator and demodulator, and realtime signal capture on 4 channels simultaneously. When paired with Tektronix' 20GHz oscilloscopes, Optametra's signal analyzers are the first commercial tools to measure and display the full optical field of coherent signals at these bandwidths. Using an open-architecture MATLAB-based computational engine, Optametra's solutions provide in-phase and quadrature eye diagrams, constellations, data waveforms, bit-error ratios (BER) for both polarizations of light in fiber and record/playback. A graphical user interface controls frequently used instrument functions.
