ITRI and Anritsu collaborate on 400GE testing platform

September 25, 2017 // By Jean-Pierre Joosting
Anritsu Corporation and Industrial Technology Research Institute (ITRI) are building a high-speed test lab to provide a bit error rate test (BERT) system with symbol rate up to 56 Gbaud PAM4 and 56 Gb/s NRZ per channel.

The BERT system will incorporate wideband optical spectrum analyzer (OSA), high-precision pulse pattern generator (PPG) and high-sensitivity error detector (ED) modules for generating high quality PAM/NRZ test signal outputs with fast Tr/Tf, low jitter and noise, and high amplitude, and supporting high-sensitivity, real-time error detection and analysis functions. It will be used for high-speed laser transceiver modules and silicon photonics related components, to accurately measure their characteristics as well as transmission and reception capabilities.

With this BERT system implementation, ITRI is expected to become the leading test lab for testing 400GE and silicon photonics related applications in Asia, giving a further booster to Taiwan’s goal of becoming a R&D centre for high-speed photoelectric devices.

The system will use the MP1800A signal quality analyzer from Anritsu, a plug-in module type BERT that can provide high quality bit error rate analysis function using built-in PPG and ED modules. Combining the MP1800A with variety of remote probe heads will allow the BERT to flexibly support both 28G/56G NRZ and 28G/56Gbaud PAM4 tests, and to output high-amplitude test signals of 4.4 Vp-p (differential, maximum). The MS9740A optical spectrum analyzer will also be used to provide high-quality analysis and signal detection for optoelectronic semiconductors and related passive components.

“With continued growth in network traffic driven by demanding of real-time audio and video, there is an urgent need for cloud data centres to support 400G Ethernet transmission, in response to explosive network data growth. ITRI will be dedicated to laser devices, photodiode and silicon photonic research and development, providing optical devices and transceiver technologies required by 400GE, thereby enhancing Taiwan’s industry capacity,” said ITRI.
