ITRI partners with Anritsu to build test lab


ITRI expected to become leading test lab for testing 400GE and silicon photonics

Industrial Technology Research Institute (ITRI), a Taiwanese research organisation, and the test and measurement firm Anritsu have 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.

The BERT system incorporates a wideband optical spectrum analyser (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 can 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 the goal of Taiwan's future plan to become a high-speed photoelectric devices R&D center.

Anritsu's Signal Quality Analyser MP1800A is 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 allows the BERT to flexible support both 28G/56G NRZ and 28G/56Gboud PAM4 tests, and to output high-amplitude test signals of 4.4 Vp-p (differential, max.).

In addition, through the multi-channel PPG sync function can controls 3Eye amplitudes of PAM4 signals independently, enables high-reproducibility evaluation of optical modulator without using an external driver amplifier. With built-in PAM4 decode and CTLE functions, the remote test platform also supports real-time PAM4 BER measurements using 28bit/s high sensitivity ED module, to improve system's test and analysis capabilities.

Furthermore, the MS9740A can also 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 centers 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.
