Broadcom advances its co-packaged optics network switch

Broadcom will provide its new 25.6-Tbps Humboldt co-packaged optics (CPO) network switch to Tencent.

Humboldt 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 closely with Broadcom to develop hardware and software for field deployment of the 25.6-Tbps CPO switch system. Ruijie Networks Co., Ltd. will verify the design, manufacture and test the full CPO switch system, and then provide the finished product to Tencent. 

The companies plan to demonstrate the jointly developed 25.6-Tbps CPO switch system at the China International Optoelectronic Exposition (CIOE) in Shenzhen from September 7th to 9th.

Humboldt 25.6-Tbps CPO Switch Product Highlights:

  • 2RU system design with high efficiency air cooling to support 4x3.2-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

Broadcom said CPO will become increasingly important for data center switches as copper interconnects approach a reach limit.  Likewise, traditional pluggable optical transceivers require high power to equalize signal impairments incurred on a signal as it traverses long traces and through multiple connector discontinuities in a standard switch system. 

The 25.6-Tbps Humboldt CPO switch leverages Broadcom's uncooled continuous wave (CW) laser at 1310 nm for silicon photonics, delivering significant power efficiency and cost gains.

Broadcom also notes that it has over 15 external partners currently working on its SCIP and CPO designs.

“We are pleased to announce our strategic partnership with Tencent as we enable the industry’s first 25.6-Tbps CPO system for hyperscale data center field deployment,” said Near Margalit, Vice President and General Manager, Optical Systems Division, Broadcom. “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.”

“Customer demands for higher bandwidth have pushed Tencent to perpetually scale our network,” said Sage Zou, Vice President of Tencent Cloud. “We are glad to partner with Broadcom on CPO based technology, which will bring not only higher bandwidth for applications such as AI/ML and HPC, but also it could address the power constraints from the acceleration of growth in new workloads.”

“Addressing the general trend towards chip-scale optical interconnects versus traditional copper-based implementation, CPO technology combines microelectronics and optoelectronics on silicon-based platforms, which can carry more information and transmit longer distances,” said Liu Zhongdong, President and CEO, Ruijie Networks. “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.”

Lumen gains FCC approval for sale of ILEC assets to Brightspeed

The FCC approved Lumen's sale of certain incumbent local exchange carrier (ILEC) assets in 20 states to Brightspeed. The deal has now received all final regulatory clearances needed to close.

Brightspeed plans to make significant investments to build an expanded fiber optics network throughout the 20-state footprint.

Safaricom tests fixed wireless access 5G slicing with Nokia

Safaricom has successfully piloted its 4G and 5G Fixed Wireless Access (FWA) network slicing on its live commercial network in Kenya in partnership with Nokia. 

The trial utilized a multi-vendor network environment and included RAN, transport and core as well as software upgrades to a range of Nokia’s products and services. The pilot demonstrated a number of solutions including Nokia’s AirScale 4G/5G base stations, the NetAct network management and assurance system and Nokia’s FastMile 4G/5G CPE.

Nokia said the trial demonstrates that Safaricom is now poised to support new types of enterprise network services, including fast lane internet access and application slicing. In addition, Nokia is enabling secured FWA slice connectivity to enterprise locations, as well as to private or public application clouds.

Network slicing enables operators the ability to divide a network into multiple virtual slices, which can be optimized for a specific target application or service. The end user of each network slice can then be serviced with different priorities, routing, levels of network performance and security capabilities. Slices can be managed and deployed in minutes, and each one has key performance indicators used for service assurance.

James Maitai, Network Director, Safaricom, said: “We are proud to have hosted Africa’s first successful pilot of 4G/5G FWA slicing on our network, and looking forward to tailoring our service offerings to individual customers and industries, to meet their needs for high-speed connectivity precisely and without unnecessary cost.
