Generate 16QAM, 64QAM CO-OFDM & More

The IQTransmitter uses high bandwidth linear RF amplifiers to enable generation of any multi-level optical modulation formats when used with RF Arbitrary Waveform Generators (AWG).

The Ideal ‘Golden’ Optical Signal Source

Generating and controlling phase modulated optical signals is made easy with the IQTransmitter. Available in three different versions; full dual-polarization, emulated dual-polarization and single polarization, you can select from the most flexible customizations commercially available. The IQTransmitter is referred to as a ‘Golden’ reference optical signal source because of its high repeatability and reliability – Every time you turn it on.

Its unrivalled high bandwidth of 40 GHz (typical) ensures high quality optical signal generation, making it the ideal optical signal source for coherent communications applications.

Full Dual-Pol M-QAM, M-PSK & Arbitrary Signal Generation

When used in conjunction with an appropriate 4 channel AWG (or two dual-channel synchronized AWG’s), fully independent Dual-Pol M-QAM optical signals can be synthesized. This enables the R&D Engineer to generate optical data streams that reflect current state-of-art long-haul optical communication systems.

Introducing the Emulated Dual-Polarization IQTransmitter

Emulated Dual-Polarization IQTransmitter
Emulated dual-polarization generation is a cost-effective solution which enables you to generate dual-polarization phase modulated signals with just two RF input channels.

The Emulated Dual-Polarization IQTransmitter can generate dual-polarization phase modulated signals by optically polarization multiplexing a delayed copy of the single-polarization modulated signal.

Pattern Independent Automatic Bias Controller

The IQTransmitter is an ideal ‘Golden Standard’ reference in terms of Repeatability and Reliability. The use of our new improved Automatic Bias Control (ABC) makes it easy for engineers to bias at a desired location. ABC’s high stability ensures that bias points are maintained at the desired location. The ABC allows engineers to work with Arbitrary modulation formats including M-QAM, M-PSK, etc. Our dedicated software for ABC offers complete remote operation capability allowing the user to control the setup even while travelling. These features make the Coherent Solutions’ IQTransmitter a superb plug-and-play R&D optical signal generator.

Intuitive GUI

Intuitive ‘IQSignal-Manager’ for More Flexibility in Modulator Bias Control
The ‘IQSignal-Manager’ is the dedicated bias control software to adjust individual bias settings or select automatic optimization, which lets you quickly and effortlessly generate optimized signals with coherent modulation format such as QPSK, 16QAM or 64QAM.
