IQScope-RT Optical Modulation Analyser

The New Zealand- based company, Coherent Solutions, together with Teledyne LeCroy, has launched a portfolio of Optical Modulation Analysers (OMA) using Coherent Solutions' IQScope technology, coupled with Teledyne LeCroy's LabMaster 10 Zi real-time oscilloscopes.

The IQScope-RT Coherent Optical Receiver is now available with standard models operating with 42 GHz and 70 GHz electrical bandwidth, the highest bandwidth commercially available for a Coherent Optical Receiver. The device is controlled via the GUI of the LabMaster.

Units with 42 and 45GHz electrical bandwidth are currently in production, with the first customer deliveries scheduled for October.  Customer deliveries of the 70GHz version are planned for January 2014.

The analyzers use Teledyne LeCroy’s LabMaster 10 Zi series of real-time oscilloscopes. With its high-speed, real-time sampling, LabMaster can perform the digital signal processing required to analyse DP-QPSK signals. LabMaster oscilloscopes allow up to 20 acquisition modules to be used with a single control module and can achieve up to 80 channels at 36GHz and 40 channels at 65GHz.

Coherent Solutions is also launching the IQScope-ERT which offers all the features of the IQScope-RT when used with a LabMaster 10 Zi, but with an additional four output channels which enable the coherent receiver to be connected to an appropriately configured equivalent-time oscilloscope. The proprietary IQScope technology enables homodyne detection techniques to be used in conjunction with the high bandwidth and vertical resolution of equivalent time oscilloscopes.

This is ideal for detailed characterization of high bandwidth transmitters. The 70 GHz IQScope-ERT coupled to an equivalent-time oscilloscope with similar or greater bandwidth can accurately analyze a 120 Gbaud modulated optical signal, capturing over 2000 data points for each transition. This is an incredibly powerful tool for 400G+ device and system developers.


As data demand ramps ever higher, researchers are looking to innovative amplifier designs to help transport a broader light spectrum through optical fibres, finds Andy Extance


Duncan Ellis shares his views about the increased focus on automation from network operators, and how the physical layer has so far stubbornly resisted the move


Switching off copper networks where fibre has been deployed is the end game, so why are so few operators doing it, wonders Pauline Rigby


With demand for fibre to the premises increasing, Keely Portway looks at the role training plays in ensuring installation skills remain available to meet this growing demand
