Optical modulation analyser supports 400G standard

The explosive growth of mobile and cloud computing continues to drive long-haul optical communications bandwidth demands. To maximize fiber optic and network infrastructure investments, the industry has turned to complex optical modulation formats that allow higher effective data rates without requiring greater network bandwidth.

To date, researchers and engineers have needed to turn to multiple test and measurement vendors or even build their own test fixtures to perform required tests, costing valuable research time and reducing repeatability. Tektronix says these introductions solve the industry-wide problem of how to efficiently test coherent modulation technologies.

“As 100G technologies start to move into the mainstream and 400G is coming into focus, we’re hearing from customers that configuration flexibility and measurement system integration are vital factors in ensuring fast time to market,” said Brian Reich, general manager, Performance Oscilloscopes, Tektronix. “In addition to offering new optical modulation receivers at 45 GHz, we now deliver the most complete coherent optical solution with the signal integrity of a 70 GHz bandwidth ATI oscilloscope and improved configuration flexibility.”

The OM4245 45 GHz Optical Modulation Analyser is capable of dual-polarisation coherent optical analysis up to 80 GBaud. It offers built-in, narrow linewidth lasers and supports the Tektronix OM-Series User Interface (OUI).  Along with proven ease-of-use for typical analysis applications, the Tektronix OUI also provides the flexibility and access to the MATLAB computational engine researchers need for more advanced coherent optical analysis. This provides a robust, time-saving, and customisable platform for conducting experiments in coherent modulation algorithms.
