Demo Showcases at OFC 2023
Broadcom will demonstrate the BCM85812 in an end-to-end link connecting two Tomahawk 5 (TH5) switches using Eoptolink’s 800G DR8 optical modules. Attendees will see live traffic stream of 800GbE data running between two TH5 switches.
Broadcom will showcase various 800G DR8, 2x400G FR4, 2x400G DR4, 800G SR8, and 800G AOC solutions from third party transceiver vendors that interoperate with each other, all using Broadcom’s DSP solutions.
Following are module vendors that will be participating in a multi-vendor interop plug-fest on the latest Tomahawk 5 switch platform:
Eoptolink,
Intel,
Molex,
Innolight,
Source Photonics,
Cloud Light Technology Limited
Hisense Broadband.
Additionally, Broadcom in collaboration with Semtech and Keysight will demonstrate a 200G per lane (200G/lane) optical transmission link leveraging Broadcom’s latest SerDes, DSP and laser technology. These demonstrations will be in Broadcom Booth 6425 at the Optical Fiber Communication (OFC) 2023 exhibition in San Diego, California from March 7th to 9th.
Broadcom Vice President and General Manager Of Physical Layer Products Division Vijay Janapaty said this first-to-market highly integrated 5nm 100G/lane DSP PHY extends Broadcom’s optical PHY leadership and demonstrates the company’s commitment to addressing the stringent low power requirements from hyperscale data center and cloud providers.
“With our advancement in 200G/lane, Broadcom continues to lead the industry in developing next generation solutions for 51.2T and 102.T switch platforms,” said Broadcom Vice President and General Manager Of Physical Layer Products Division Vijay Janapaty.
Wheeler’s Network Principal analyst Bob Wheeler said by 2028, optical transceivers are projected to account for up to 8% of total power consumption in cloud data centers.
“The integration of TIA and driver functions in DSP PHYs is an important step in reducing this energy consumption, and Broadcom is leading the innovation charge in next-generation 51.2T cloud switching platforms while also demonstrating a strong commitment to Capex savings,” said Wheeler’s Network Principal analyst Bob Wheeler.
