Coherent Solutions offers new modules for MTP test platform

Coherent Solutions has introduced five new modules for its MTP modular optical test platform for manufacturing and research and development environments. The company has also developed a smaller version of the test platform.

The new MTP modules add more functionality to the optical engineer’s toolbox while improving testing efficiency and reducing workspace clutter. They include:

Coherent Solutions automates polarisation dependent testing

Coherent Solutions has added a new functional module to its MTP1000 modular test platform. The PolBlade is the new polarisation controller module that adds automatic polarisation control functionality to the test automation platform. Its addition allows users to achieve remote operation and automation of polarisation dependent testing from one MTP1000 mainframe.

The user can adjust three voltage settings of the PolBlade to control the polarisation, or it can be put into scrambling mode, which gives fast and even coverage of all states of polarisation.

IQ-Modulator Auto-Bias Control: Linchpin to Optical Arbitrary Waveform Generation

Modern high bit rate optical communication channels now use polarization, amplitude and phase of the optical carrier to encode digital information. The future of optical communication requires Optical Arbitrary Waveform Generation (O-AWG). The ability to produce any kind of optical waveform, through the use of an optical modulator and an electrical AWG requires better accuracy and reliability than ever before. O-AWG’s require full control of an optical modulator, including the ability to bias at any arbitrary point on the modulator's electrical-to-optical transfer functions. The needs of the research and development community are ever changing and a truly arbitrary O-AWG will be as necessary to the optical R&D engineer as is the electrical AWG is for the RF engineer.

Coherent Solutions introduces automatic bias controller for IQ-modulators

Coherent Solutions of Auckland, New Zealand, has launched the IQABC, a pattern independent automatic bias controller for IQ modulators used by engineers developing the next-generation of high-speed coherent optical systems.

The IQABC enables full control of an IQ-modulator’s DC biases, in automatic or manual mode, and is modulation format independent, paving the way towards simple generation of any conceivable optical signal.

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.

IQScope-RT Optical Modulation Analyser

The New Zealand- based company, Coherent Solutions, together with Teledyne LeCroy, has launched a portfolio of Optical Modulation Analysers (OMA) using Coherent Solutions' IQScope technology, coupled with Teledyne LeCroy's LabMaster 10 Zi real-time oscilloscopes.

The IQScope-RT Coherent Optical Receiver is now available with standard models operating with 42 GHz and 70 GHz electrical bandwidth, the highest bandwidth commercially available for a Coherent Optical Receiver. The device is controlled via the GUI of the LabMaster.
