Keysight Technologies, Inc. and Credo Semiconductor set a new milestone by developing a joint testbed that demonstrates the first IEEE P802.3dj draft specification compliant 1.6 terabit (T) Ethernet measurement system running full line rate layer 2 Ethernet traffic on a real world hardware development platform. This demonstration provides proof that 1.6 terabit speed is possible and that its performance can be measured. To keep pace, network equipment manufacturers, silicon chip manufacturers, and data center operators must build and operate next generation 1.6T Ethernet networks.

To help data center operators overcome any potential hurdles, network equipment and chip manufacturers must: Deliver higher speed and data throughput without increasing data center power and cooling requirements; Implement faster electrical lane speeds for the communication chips embedded in optical transceivers, switches, routers, servers, and test systems without compromising reliability or quality; Measure the performance of silicon chips, network equipment, and network interconnection devices during their quality assurance (QA) cycle in final product benchmark testing. In recognizing the challenges of deploying 1.6T Ethernet, Keysight, developed the industry's first working 1.6T Layer 2 traffic generation and measurement system, and is demonstrating it in a joint testbed with Credo. As 1.6T adoption gains momentum, establishing a testing framework early in the product development life cycle is critical to help speed time to market and enable confident deployment.

Keysight, a leader in 400GE and 800GE testing is now helping companies prepare their 1.6T development plans and has the measurement systems needed for early adopter testing. Highlights of the Keysight and Credo testbed demonstration include: Operational 1.6T Layer 2 engine - The engine operates on an interface of 16 electrical lanes running at 106.25 gigabits per second (Gbps) per lane with Pulse Amplitude Modulation 4 (PAM4) signaling and Forward error Correction (FEC). This is also called 16 x 100G SERDES.

Keysight hardware development test platform -With OSFP-XD front panel ports that can send and receive full line rate 1.6T layer 2 bi-directional traffic over a Credo provided 2-meter HiWire Active Electrical Cable (AEC). End users can utilize FEC measurements to assess the resilience of network equipment under different stress conditions, so they can confidently deploy devices, interconnects, and networking equipment into their production networks.
