The IQS series of Coherent Optical Receivers extends Teledyne LeCroy’s Optical Modulation Analysis (OMA) range. When combined with the 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 130 GBaud.
The result of several years of collaboration with the optical specialists at Coherent Solutions , the 70-GHz Teledyne LeCroy IQS70 Coherent Optical Receiver pairs with the LabMaster 10-65Zi-A oscilloscope to provide a system bandwidth of 65 GHz, delivering a solution for characterising 56-Gbaud communications systems and enabling detection up to 130 GBaud. For lower-rate applications, the 42-GHz IQS42 Coherent Optical Receiver provides a test platform for up to 32-Gbaud DP-16QAM or DP-QPSK when used with the 36-GHz LabMaster 10-36Zi-A.
Completing the offering, Optical-LinQ is a fully integrated software package for measurement and visualisation of optically modulated signals. It runs entirely within the user interface of the LabMaster 10Zi-A for integrated control of both oscilloscope and coherent receiver. Optical-LinQ provides fully automated control of the IQS receiver, phase recovery algorithms, and polarisation demultiplexing, as well as a complete suite of modulation analysis displays and parameters.
In addition to system bandwidth of 70 GHz, 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.
