Anritsu and Industrial Technology Research Institute (ITRI) announced a collaboration to build a high-speed test lab to provide a bit error rate test (BERT) system with symbol rate up to 56Gbaud PAM4 and 56Gb/s NRZ per channel.
According to ITRI, “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. The Taïwanese institute will be dedicated to laser devices, photodiode and silicon photonic research and development, providing optical devices and transceiver technologies required by 400GE.
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 & 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.
The system will use Anritsu’s Signal Quality Analyzer MP1800A, a plug-in module type BERT that can provide 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 support both 28G/56G NRZ and 28G/56Gbaud PAM4 tests, and to output amplitude test signals of 4.4 Vp-p (differential, max.). The Optical Spectrum Analyzer MS9740A will also be used to provide analysis and signal detection for optoelectronic semiconductors and related passive components.
