All demos are PAM4, does this rule Macom out as POET's partner?

As it is not attending the Optical Networking and Communication Conference & Exhibition (OFC 2020) in San Diego (8-12 March) due to increased concerns over the spread of the COVID-19 virus, MACOM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) is conducting product demonstrations directly from its US design centers to its worldwide customers in private, one-on-one interactive demonstrations by video conference.

MACOM is utilizing video conferencing to showcase its newest optoelectronic and photonic products and components. Demonstrations are available to customers on 8-12 March during regular show hours, and are scheduled to commence every 30 minutes, between 9am and 5pm PT. Demonstrations are hosted by MACOM’s optical and high-speed data design and applications engineering teams. Customers have the opportunity to ask questions and interact with MACOM staff during the demonstrations.

Live streaming video demonstrations include:

DEMO #1: 100Gbps DR/FR PAM4 Product Demonstration. Leveraging MACOM’s latest PRISM digital signal processor (DSP), 53Gbaud transimpedance amplifier (TIA) and high-speed photodiode, this demonstration showcases an operating 100Gbps DR/FR PAM4 link over 2km of fiber. This chipset is suited to point-to-point or 4 x 100Gbps breakout applications in the data center.

DEMO #2: Secure 50Gbps PAM4 Mid Haul for 5G Wireless. This demonstration showcases a complete 50Gbps PAM4 transmit and receive link over 10/20km fiber with Ethernet security. It features five MACOM ICs including the new PRISM-50 DSP, silicon photonics, 26Gbaud TIA and high-speed photodetector. Ethernet security is provided by MACOM’S dual 100Gbps MACSec PHY, which also features both RS(544, 514) and RS(528,514) FEC.

DEMO #3: 100Gbps PAM4 Customer Interoperability. This demonstration highlights MACOM’s latest 100Gbps single-lambda PAM4 DSP chip in a leading OEM’s 100G FR QSFP28 module. This exhibit includes a PAM4 100Gpbs bi-directional link covering both 2km and 10km on single-mode fiber.

DEMO #4: 200/400Gbps PAM4 Open Eye MSA Solutions. This demonstration showcases MACOM’s high-speed analog chipset in modules that are compliant with the 200Gbps Open Eye MSA standards. It includes single-mode modules and 200Gbps and 400Gbps multi-mode active optical cable (AOC) modules plugged into commercial Ethernet switches supporting QSFP and QSFP-DD slots with 4x53Gbps and 8x53Gbps electrical interfaces. MACOM is demonstrating that its analog chipset is interoperable with IEEE-compliant DSP-based modules.
