DS4000 
Overview
The Celestica DS4000 is a 1RU open network switch with 32×QSFP-DD 400GbE ports, delivering up to 12.8Tbps switching capacity. Designed for high-density leaf/spine fabrics and dynamic aggregation layers, it supports flexible port breakout (from 10G to 400G), precision timing, and SONiC-ready software compatibility. Built for performance, the DS4000 combines low latency, high reliability, and power-efficient design in a compact form factor for modern data centers.
