Keysight AresONE 800GE QSFP — DD800-M 4/8-Port Test Systems

Challenge: Testing all speeds from 10GE to 800GE

The 800GE component ecosystem has evolved rapidly. Most major networking companies are developing networking equipment that have 800GE front panel and/or upload ports. The same PAM4 encoded signaling and Forward Error Correction (FEC) technologies, that were widely adopted for 400GE ports, are being used with 106.25Gb/s (namely, 53 Gbaud) electrical lane front panel interfaces for 800GE. Switch ASICs now support up to 106.25Gb/s lanes with PAM4 modulation and FEC—easing the transition from 400GE to 800GE. Testing new port speeds 1x800GE, 2x400GE, 4x200GE, and 8x100GE is the new challenge, however, testing legacy 400GE and 100GE speed is also essential. Bandwidth requirements for internet applications are driving the need for testing line-rate traffic of 25.6 and 51.2 Tbps networking equipment.

Keysight has extended its industry leading AresONE 800GE platforms to support all the 800GE, 400GE and 100GE PAM4 and NRZ related speeds to address ever-increasing market test needs.

Solution: All-In-One Test Platform with 8-Port Density and 800GE, 400GE, and 100GE Speeds

With several first-to-market solutions, AresONE 400GE, AresONE High Performance 400GE and the high density, 16-port AresONE-S 400GE chassis with PAM4 and NRZ signaling support have established a significant footprint as enablers for testing 400GE technology. Now, AresONE 800GE QSFP-DD800-M is our latest innovation to the AresONE high-speed Ethernet family.

The AresONE 800GE 4-port and 8-port 800GE models provide up to 6.4Tbps of test traffic bandwidth and measurement. The chassis are stackable to build higher-throughput and port-count testbeds, up to 64-ports of line-rate 800GE traffic generation and performance measurement in a single configuration. Even if you do not need 8-ports of 800GE today, 2-port and 4-port offerings are available with field upgrades that provide an expandable test platform that can grow with your test bandwidth needs.

AresONE 800GE enables testing of multiple Ethernet speeds in the same platform with each port capable of the following speeds:

• Built-in PAM4 signaling speeds based on 106.25 Gb/s host electrical lanes: 2x400GE, 4x200GE, and 8x100GE per port

• Built-in PAM4 signaling speeds based on 53.125 Gb/s host electrical lanes: 1x400GE, 2x200GE, 4x100GE and 8x50GE per port

• Optional NRZ signaling based on 26Gb/s host electrical lanes: 1x200GE, 2x100GE, 8x25GE, 4x50GE, 2x40GE, and 8x10GE over 10Gb/s electrical lanes per port

• 1x800GE is a separate purchasable option with the initial order from the factory or later with a field upgrade

Pay as you Grow — Full and Reduced, Speed Variants, All Field Upgradeable

AresONE 800GE QSFP-DD800-M fixed chassis are available in 8-port, 4-port, and 2-port with full- and reduced-performance model selections:

• 8-port hardware chassis — Full and Reduced Performance models

• 4-ports enabled on the 8-port hardware chassis — Full and Reduced Performance models

• 4-port hardware chassis — Full and Reduced Performance models

• 2-ports enabled on the 4-port hardware chassis — Full and Reduced Performance models

Chassis Port Count Upgrades — Increase the density of your test bed

Keeping with the trend set by earlier generation of AresONE 400GE, next generation AresONE 800GE offers flexibility for port upgrades for installed chassis based on growing requirements for more test ports. Users can field-upgrade from the existing 2-port enabled configuration to the 4-port configuration, and the 4-port enabled configuration to the 8-port configuration. See the Ordering section for more information.

Chassis Upgrades — Grow your feature set and protect your investment in your original AresONE 800GE test system.

Keysight offers a unique capability in the test and measurement industry that provides a hardware upgrade pathway to increase the capability and the functionality of your 800GE test system in a significant way. An existing AresONE 800GE (the first generation) and the AresONE-C (secondgeneration) hardware electronics can be upgraded as per the table shown later. This is a return-to-factoryhardware electronics upgrade that allows you to keep your existing serial number asset and it adds major functionality.
