Broadcom and Tencent develop CPO network switches for cloud

Broadcom and Tencent announced a partnership for the adoption of co-packaged optics (CPO) network switches for cloud infrastructure.
Tencent MusicBroadcom will provide the 25.6-Tbps Humboldt CPO switch device that features Broadcom’s StrataXGS Tomahawk 4 switch chip directly coupled and co-packaged with four 3.2-Tbps Silicon Photonics Chiplets In Package (SCIP) optical engines.

Tencent has defined the system architecture and worked with Broadcom to develop hardware and software for field deployment of the 25.6-Tbps CPO switch system.

Ruijie Networks will verify the design, manufacture and test the full CPO switch system, and provide the finished product to Tencent.

The 25.6-Tbps CPO switch system will be demonstrated at the China International Optoelectronic Exposition (CIOE) in Shenzhen from September 7-9.

25.6-Tbps CPO Switch Product Highlights:

2RU system design with high efficiency air cooling to support 4×3.2-Tbps optical CPO interfaces routed to 16 MPO connectors and 32x400G electrical QSFP112 ports

CPO engine to front-panel routing supports both traditional fiber and flexible printed fiber (FPF) solutions

System design compatible to support multiple remote laser modules (RLM)

More than 50% optical interconnect power consumption savings compared to standard pluggable optics solutions

Production ready for data center deployment

“We expect to continue to innovate and extend our market leadership position with Tencent as we migrate to 51.2-Tbps switch CPOs and next generation 200G/lane PAM-4 applications,” Near Margalit, Vice President and General Manager, Optical Systems Division, Broadcom, said.

“We partner with Broadcom on CPO based technology, which will bring higher bandwidth for applications such as AI/ML and HPC,” said Sage Zou, Vice President of Tencent Cloud.

“CPO switching networks have the advantages of high bandwidth and low power consumption, and Ruijie is glad to participate in the innovation and implementation of this new technology with Tencent & Broadcom,” Liu Zhongdong, President and CEO, Ruijie Networks, said.
