Performance Leading Next Generation IQ Reference Transmitter
The fully integrated optical frontend that converts differential electrical RF signals into dual-polarization IQ-modulated optical signals has been developed in cooperation with ID Photonics in Munich, Germany, supporting research for multi-terabit capacity optical communication systems. ID Photonics specializes in next-generation test and measurement instruments for coherent transmission solutions.
The IQ Modulator Optical Multi-Format Transmitter is a fully integrated instrument available in multiple bandwidth classes:
- Class 80: Bandwidth >80 GHz, supporting symbol rates up to 170 GBaud/s
- Class 60: Bandwidth ~60 GHz, supporting symbol rates up to 120 GBaud/s
- Class 40: Bandwidth >40 GHz, supporting symbol rates up to 96 GBaud/s
It converts differential electrical RF signals into various optical modulation formats (such as QPSK and m-QAM) utilizing a high-bandwidth dual-polarization IQ Mach-Zehnder-based optical modulator and offers an optional high-fidelity tunable laser source.
