World Leading Automatic Bias Controller for IQ-Modulators
Coherent Solutions’ IQABC with its advanced ABC (Automatic Bias Control) algorithm, accurately and reliably controls and optimizes all the modulator bias points regardless of the modulation format or pattern. Now you just need to hit the AUTO button and focus on your research without worrying if your modulator is biased correctly.
Optimizing DC bias points of an IQ modulator is no trivial task. There are six different Mach-Zehnder structures inside one dual polarization IQ modulator, all simultaneously influencing the properties of a single optical signal. Trying to optimize bias points using just the intensity measurement of the optical signal is time consuming, inaccurate and it requires a lot of knowledge and experience.
But worry no more, IQABC is here to help. With its robust and adaptive ABC algorithm, IQABC will take care of finding optimal bias points and maintaining optimization against any bias drifts or changes to the driving signal. So put IQABC to work and enjoy having a stable and reliable optical signal for all your testing and development needs.
'We are delighted to have the IQABC -bias control module in our laboratory. It saves us a lot of time and effort in setting up our experiments. Its robustness to baud rates and modulation formats is remarkable. The device also comes with a well-designed GUI which adds to the convenience. We are also very pleased with the technical support from Coherent Solutions which not only includes timely replies to our queries and concerns but also regular inquiries from their side to keep our needs satisfied. Overall, we are very pleased with everything Coherent Solutions has offered us.' Stephen E. Ralph

Modulation format independent ABC algorithm
The robust ABC algorithm works with any modulation formats for a truly automated operation.
Independent control of all DC biases
Each of I, Q or Phase DC biases can be controlled independently in either automatic or manual mode.
Accurate & stable tracking of bias drifts
The advanced ABC algorithm constantly tracks any drift, so you get stable and repeatable results every time.
Compatible with OIF standard IQ modulators
The external modulation adaptor board provides simple and quick connectivity to any IQ Modulator with OIF compatibility.
You can control IQABC locally or remotely via USB or Ethernet. With SCPI compatibility the choice is yours.
Easy to use software
IQABC software controller provides access to all the functions in a clean, simple and intuitive graphical interface.
All Coherent Solutions’ products come with a standard 3 year warranty.
Convenient and simple to operate
Simply connect your OIF compliant IQ modulator to an IQABC modulator adaptor board and feed the modulator’s optical output to IQABC, then you are ready to go! IQABC starts to optimize the biases automatically upon start-up.
Intuitive Graphical User Interface (GUI)
IQABC can be operated in stand-alone mode using its built-in front panel control and display. It also comes with a feature complete control software, IQSignalManager, which is an intuitive and easy-to-use GUI. With IQABC’s Ethernet connectivity, you can access and control the unit from anywhere within your local access network and even automate the control using SCPI commands.
