Coherent Solutions debuts IQTransmitter for 56Gbaud test

Coherent Solutions of Auckland, New Zealand, has chosen ECOC 2015 in Valencia, Spain to launch its 40GHz IQTransmitter, the IQTX-40.

The IQTX-40 is the first fully integrated laboratory optical transmitter with 40GHz of RF bandwidth, according to the company, providing R&D engineers with the instruments they need to generate coherent modulated signals using baud rate up to 56Gbaud.

The new IQTX-40 features a new automatic bias control (ABC) that optimises the performance of the modulator irrespective of the modulation format being used. Engineers can now seamlessly change modulation formats and baud rates without any concerns about maintaining the modulator’s bias stability.

The instrument is available in multiple configurations, including full dual polarisation, emulated dual polarisation and single polarisation. The new ABC also allows the user to individually control the bias locations of all biases of the modulator, enabling it to generate a variety of signals beyond coherent modulation.

As with all instruments available from Coherent Solutions, the IQTX-40 can be fully controlled remotely with SCPI/VXI11 commands making it easy to control from Matlab, Python, LabView or any other environment.

“Coherent Solutions is dedicated to providing the highest, most reliable performance and simple-to-use test instrumentation for optical communications R&D,” said Andy Stevens, CEO of Coherent Solutions. “Our new IQTransmitter enables researchers and engineers to generate coherent modulated optical signals with unmatched bandwidth, quality, and stability of data rates beyond 400Gb/s.”

The new IQTX-40 will be demonstrated on the Teledyne LeCroy stand #548 at ECOC 2015, and is commercially available now.
