Juniper QSFP-DD800 to 4 x 200G QSFP56 DAC 1M | 800G Breakout, Enterprise

Consolidate high-speed connectivity without adding optical modules. This Juniper breakout DAC maps one QSFP-DD800 interface to four 200G QSFP56 connections, giving infrastructure teams a direct path for short-reach aggregation, leaf-spine expansion, and high-density switch-to-switch designs. At 1 m, it is suited to adjacent rack and same-cabinet deployments where signal integrity and cable management matter more than reach. Direct attach copper avoids the cost and power overhead of separate transceivers, while preserving the deterministic behavior expected in tightly controlled data center fabrics. For teams standardizing on 200G building blocks, this cable supports clean port fan-out from a single high-capacity uplink. That makes it a practical choice when you need to scale bandwidth efficiently, keep BOM complexity down, and maintain a compact physical footprint in production racks.
