Teledyne LeCroy, Anritsu Company, Coherent Solutions Ltd. and Oclaro, Inc.  have announced a new joint effort to demonstrate the highest performance single-carrier 16QAM signal generation and analysis capabilities available at 56Gbaud. The demonstration of the partners’ latest optical communications test equipment platform takes place at OFC 2016 in Anaheim, CA, USA in the Teledyne LeCroy booth #1115.

The platform incorporates the highest-performance equipment available for generating, transmitting, receiving and analysing coherent optical signals at 400G rates. Anritsu’s MP1800A Signal Quality Analyzer and G0361A high-speed DAC generate the high-quality 56Gbaud, PAM4 RF signal (112 Gbps). Coherent Solutions’ IQTransmitter then uses Oclaro’s latest 40GHz LiNbO3 modulator to turn these PAM4 RF signals into an optical 16QAM signal.

New modulation-format-independent Automatic Bias Control (ABC) technology, also from Coherent Solutions, automatically optimizes and stabilizes the signal. Teledyne LeCroy’s 65GHz LabMaster 10-65Zi-A high-bandwidth real-time oscilloscope combines with the 70GHz IQS70 coherent optical receiver and Optical-LinQ integrated OMA software to accurately characterize the modulated optical signal.

Anritsu’s MP1800A Signal Quality Analyzer (SQA) is a Bit Error Rate tester offering a comprehensive suite of test capabilities to support complete signal and transmission integrity analysis. In the demonstration, the MP1800A will be integrated with the G0361A, a 64Gbaud 2-bit D/A Converter (DAC) with dual-channel 2×1 multiplexers.

Coherent Solutions’ new IQTransmitter offers an unparalleled 40GHz of RF bandwidth and incorporates the 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 16QAM.

The Oclaro 400G LiNbO3 external modulator is the industry’s first device explicitly designed to enable speeds of 400G and beyond on a single wavelength or carrier.

Teledyne LeCroy’s Optical Modulation Analysis solution provides the industry’s best performance by combining the highest bandwidth with the most flexible analysis. The 70GHz bandwidth IQS70 Coherent Optical Receiver integrates seamlessly with the world-leading LabMaster 10Zi-A oscilloscope and OpticalLinQ software, delivering the most complete optical modulation analysis package.

The joint demonstration will be on display at the Teledyne LeCroy booth #1115. A second set up will be on display at Oclaro booth #1601.
