The IQS series of Coherent Optical Receivers extends Teledyne LeCroy’s Optical Modulation Analysis (OMA) portfolio, enabling the creation of flexible, modular systems. When combined with Teledyne LeCroy’s LabMaster 10Zi-A oscilloscopes and integrated Optical-LinQ analysis software, the IQS receivers test DP-QPSK and DP-16QAM optical signals at speeds up to 130GBaud.
The result of several years of collaboration with the optical specialists at Coherent Solutions, the 70GHz Teledyne LeCroy IQS70 Coherent Optical Receiver pairs with the LabMaster 10-65Zi-A oscilloscope to provide a system bandwidth of 65 GHz, delivering an ideal solution for characterising leading-edge 56Gbaud communications systems and enabling detection up to 130GBaud.
For lower-rate applications, the 42GHz IQS42 Coherent Optical Receiver provides the test platform for up to 32Gbaud DP-16QAM or DP-QPSK when used with the 36GHz LabMaster 10-36Zi-A.
The instruments are complemented by Optical-LinQ, an intuitive and fully integrated software package for measurement and visualisation of optically modulated signals. It runs entirely within the user interface of the LabMaster 10Zi-A and it enables integrated control of both oscilloscope and coherent receiver.
Optical-LinQ provides fully automated control of the IQS receiver, phase recovery algorithms, and polarization demultiplexing, as well as an exhaustive number of modulation analysis displays and parameters.
In addition to a bandwidth of 70GHz, these Optical Modulation Analysis systems provide a dynamic calibration capability to enable the LabMaster 10 Zi-A real-time oscilloscope to be disconnected from the IQS Coherent Optical Receiver and used for other electrical validation and testing without requiring a factory re-calibration.
This enables dual use of the oscilloscope for serial-data eye diagrams and jitter, noise and crosstalk analysis on NRZ electrical tributaries using Teledyne LeCroy’s SDAIII-CompleteLinQ software package.
Teledyne LeCroy will demonstrate an OMA System consisting of an IQS70 receiver and a LabMaster 10-65Zi-A oscilloscope system at the ECOC Exhibition in Valencia (September 27-October 1).
