Optical modulation analyser

4 April 2012 Test & Measurement

Agilent Technologies has introduced a portable, fully integrated optical modulation analyser with a laptop-size screen. The compact design and affordable price make the new N4392A relatively accessible to all engineers who need to analyse complex modulated optical signals during development and manufacturing of 40/100G coherent transmitters and receivers.

The instrument enables engineers to characterise components like in-phase quadrature modulators and integrated coherent receivers designed according to industry standards for 100G coherent transmission. The integrated design accelerates setup and eliminates configuration effort so users can focus on design challenges. Built-in performance verification and recalibration routines deliver high-confidence test results and extend the recommended recalibration period, improving uptime and lowering the cost of ownership.

Agilent used today’s most advanced integrated circuit technology to create the first optical modulation analyser in the form factor of a mid-size oscilloscope. The smaller size allows for true portability. A 15” analysis screen shows more information at the same time, making it easier for engineers to characterise complex modulated optical signals.

In addition to the features currently available in other optical modulation analysers, the N4392A offers four differential RF input channels to help engineers characterise integrated coherent optical receivers. This makes the new instrument an ideal tool for R&D engineers involved in 40/100G characterisation and debugging. The ability to analyse signals correctly whenever needed increases the engineers’ insight into the nature of complex modulated optical signals and helps them avoid possible pitfalls in their designs.

For 400 Gbps to 1 Tbps next-generation transmission rates, Agilent offers the N4391A optical modulation analyser enabled by Agilent’s 90000 X-Series oscilloscopes.

The new optical modulation analyser family offers novel signal-processing algorithms for modulation-format-transparent polarisation alignment and phase tracking. The family also offers chromatic dispersion and first-order polarisation mode-dispersion measurement and compensation. All modulation analysers provide a defined interface to customer-developed MATLAB algorithms. This feature enables consistent results from early research to final manufacturing qualification, including the exchange of configuration files.
