Optametra Coherent Lightwave Signal Analyzers available for 100G physical layer test

SEPTEMBER 21, 2009 -- Optametra has announced the availability of its OM4105 and OM4106 Coherent Lightwave Signal Analyzers with bit rates to 112 Gbps (100G DP-QPSK). The higher data rate is also available as an upgrade to those who have already purchased the OM4005 and OM4006 40G analyzers, announced previously at OFC/NFOEC 2009. Both the 40G and 100G versions of the OM4000 analyzers enable simultaneous measurement of any fiber modulation format, including coherent dual-polarization quadrature phase-shift keying (DP-QPSK), and subsets such as differential QPSK.

"Optametra's OM4000 series analyzers capture the complete electric field of the optical signal; they are universal, and measure everything that can be known about the signal -- within the bandwidth of the digitizer or oscilloscope -- while not taking shortcuts at the expense of losing valuable data," saysDaniel van der Weide, the company's vice president of engineering.

Optametra's software calibrates and processes real-time burst-mode constellation diagram displays, eye-diagram displays, bit-error-rate detection (BER), polarization (Poincaré sphere), and more. The upgradable software addresses applications such as polarization scrambling, recirculating loops, and arbitrary (user-defined or PRBS) patterns, which means it is useful for actual transmission experiments, not only for tuning a transmitter. Additionally, Optametra's Pro-version software option allows customers access to all variables in the analysis via Matlab, providing a platform for developing and testing proprietary algorithms including chromatic-dispersion compensation, polarization-mode dispersion compensation, new proprietary modulation schemes, pass-fail criteria, or any idea that can be coded in Matlab. "The OM4000 series of 100G Coherent Lightwave Signal Analyzers are perfectly suited for the R&D lab, production floor, and final test," says Rob Marsland, president of Optametra.

The OM4105 and OM4106 100G analyzers may be ordered now, with standard lead times of 12 weeks ARO, depending on configuration and current availability. Optametra's products work with all four-channel 40 Gigasample/s or faster real-time oscilloscopes, including those from Tektronix, Agilent, and LeCroy.
