Luton, UK, Auckland, NZ, San Jose, CA, and Chestnut Ridge, NY. Teledyne LeCroy, Coherent Solutions Ltd, Oclaro Inc., and Anritsu EMEA Ltd. announced they will be demonstrating the industry’s first commercially available R&D platform for testing single-carrier coherent optical communication systems and components operating at 56 GBaud and beyond at ECOC 2015 in Valencia, Spain, through October 1.
This development platform is available now and features what the companies believe to be the highest baud-rate single-channel optical communications test and measurement system achievable today using commercial instrumentation.
Research and development groups across the globe are striving to achieve higher and higher optical data transmission rates. High bandwidth signal generation and analysis tools are essential to development of the new technologies, components, and higher-order modulation formats being investigated to support the insatiable global demand for bandwidth. This demonstration is intended to showcase how high baud-rate optical signals can be reliably generated, optimized, and analyzed through the careful integration of leading-edge equipment from the right suppliers.
56-GBaud electrical signals are generated by Anritsu’s MP1800 Signal Quality Analyzer used in combination with its MP1861A MUX. The 40-GHz IQTransmitter from Coherent Solutions translates this into an emulated dual-polarization optical signal, enabled by the integration of Oclaro’s 400G single-carrier LiNbO3 modulator.
The performance of the optical transmission system is then analyzed by the Teledyne LeCroy 10-65Zi-A OMA system incorporating the new IQS70 70GHz Coherent Optical Receiver and OpticalLinQ software.
Anritsu’s MP1800A Signal Quality Analyzer is a bit error rate tester offering a comprehensive suite of testing capabilities to support complete signal and transmission integrity analysis. Anritsu MP1800A Signal Quality Analyzer’s key features include superior signal waveform quality, extremely low intrinsic jitter and fast transition times, multichannel generation and analysis, integrated full jitter tolerance stress generation, 4Taps Pre-Emphasis, and PAM4 and PAM8 Converters. Anritsu has also announced another evolution for this platform to cover signal generation, analysis and jitter tolerance testing up to 64.2 Gb/s, as a worldwide solution for R&D on signal transmission up to 1 Tb/s
The new IQTransmitter offers 40 GHz of RF bandwidth and also incorporates new modulator automatic bias control (ABC) circuitry, which provides fully pattern-independent bias control. This is a critical capability for the investigation of higher order modulation formats such as 16-QAM. The 40-GHz IQTransmitter from Coherent Solutions provides research, development, and production environments with a stable, coherently modulated optical signal for component and system characterization. “We are very pleased to be able to show-case our new release of the IQTX-40 in this system which sets a new standard for high baud-rate optical signal generation and analysis instrumentation,” stated Andy Stevens, CEO of Coherent Solutions.
The Oclaro 400G LiNbO3 external modulator has been explicitly designed to enable 400G and beyond speeds on a single wavelength or carrier. “By eliminating the need to use two wavelengths with the 16-QAM modulation format, Oclaro’s new modulator will enable customers to accelerate the design and test of next generation, high-speed 400-Gb/s networks,” said Adam Carter, chief commercial officer at Oclaro. “We are pleased to see our modulator being used in this industry-first development platform as this represents a major milestone in the design, test and delivery of higher-speed networks that carriers are demanding.”
Teledyne LeCroy’s Optical Modulation Analysis solution combines high bandwidth with flexible analysis. The 70-GHz bandwidth IQS70 Coherent Optical Receiver integrates seamlessly with the 10Zi-A oscilloscope and OpticalLinQ software. “Consistent bandwidth leadership means Teledyne LeCroy oscilloscopes have become crucial tools for those pushing the boundaries of optical communications technology,” said Patrick Connally, product manager for high-performance oscilloscopes at Teledyne LeCroy. “Our complete optical modulation analysis solution, including our new IQS receivers, enable us to continue that trend in this leading-edge development platform.”
