Technologies and Products

Anritsu Corporation and CIG Photonics will jointly demonstrating a new 800G optical transceiver PAM4 test solution in the Anritsu booth (#7B33) at CIOE 2022. The test setup will input an 8-lane optical signal from a CIG QSFP-DD800 2xFR4 800G optical transceiver to Anritsu’s MP2110A Sampling Oscilloscope to demonstrate measurement of key test parameters, including TDECQ (Transmitter and Dispersion Eye Closure Quaternary).

With a built-in CRU (Clock Recovery Unit), the MP2110A 4ch sampling oscilloscope can analyse NRZ (Non-Return to Zero) and PAM4 eye patterns of 10G-800G optical transceivers and devices. The demonstration will use two MP2110A units to measure and analyse 800G optical transceiver 8-lane optical signals in parallel and cuts evaluation times by 50, says Anritsu.

The 800G transceiver under test will be a CIG QSFP-DD800 2x400G-FR4 module. The optical interface conforms to 400GBASE-FR4 interface using dual 53.125 Gbaud PAM4 CWDM. The electrical interface conforms to 400GAUI-4 using 8-lane 53.125 Gbaud PAM4. The transmission distance is 2 km, and the max. power consumption is 16 W.

CIG Photonics Japan vice president and chief technical officer Koichi Tamura says, “The demand on 800G optical transceivers is strengthening due to rapidly increasing traffic in hyper-scale data centres and it is expected to be in mass-production for 25.6 Tbps switch applications in CY2023. At this time, we are very pleased to be cooperating with Anritsu with our high-quality and low-cost 800G optical transceivers based on our long-term experience in high-speed and high-density design and packaging technologies.”

Kohei Ota, general manager of Anritsu’s Service Infrastructure Solutions Division says, “Anritsu is continuing to develop unique test solutions supporting improved optical transceiver development and mass-production efficiency. I am very proud of this joint demonstration with CIG of their leading-edge 800G optical transceiver. In addition to these solutions, we will continue to contribute to the realisation of next-generation networks with increasing speed and capacity by providing device and network test solutions.”
