Active Electrical Cable Technology for Keysight 400GE to 4x100GE with PAM4-to-NRZ Conversion

Show Description

Keysight’s AresONE, AresONE High Performance, AresONE-S, and K400 400GE test systems are the first to bridge the signaling gap between incompatible pulse amplitude modulation level 4 (PAM4) and non-return-to-zero (NRZ)-encoded signaling. Keysight 400GE AresONE, AresONE High Performance, AresONE-S, and K400 400GE test systems offer a new and unique innovative AEC cable technology that allows a single port of 400GE with PAM4 and KP4 FEC to test four ports of 100GE with NRZ and RS (528,514) FEC. RS (528,514) FEC is also known as KR4 FEC.
