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.
