400G QSFP-DD to 2x200G QSFP-DD Passive DAC (0.5-3m) Description
Our EDGEOPTIC 400G-PDAC-QSFP-DD-2xQSFP-DD is a multi-vendor compatible 400G QSFP-DD passive direct attach copper breakout cable designed for ultra-high-performance 400 Gigabit Ethernet applications in advanced data center environments. The cable features a breakout configuration with a single QSFP-DD (Quad Small Form Factor Pluggable Double Density) connector on one end and two QSFP-DD connectors on the other, enabling flexible 1-to-2 connectivity for high-density 400G network architectures, including spine-leaf topologies and hyperscale deployments.
The cable supports multi-rate operation from 212.5 to 425 Gbps, allowing it to operate as a 400G link while providing breakout capability into two independent 200G high-speed channels. This flexibility supports evolving network designs that require scalable bandwidth distribution and efficient port utilization across modern switching platforms.
As a passive DAC solution, the 400G-PDAC-QSFP-DD-2xQSFP-DD requires no external power and introduces near-zero latency, making it ideal for short-reach interconnects in latency-sensitive environments. The cable is optimized for distances between 0.5 and 3 meters and utilizes high-quality 28 AWG twinax copper construction to ensure reliable signal integrity and stable performance at high data rates, including PAM4 signaling.
The electrical interface conforms to QSFP-DD MSA specifications, ensuring broad compatibility with standard QSFP-DD host systems from multiple vendors. The cable supports DDM/DOM (Digital Diagnostic Monitoring), enabling real-time access to key operational parameters such as temperature and voltage for improved network visibility and proactive maintenance.
Designed for operation within a standard temperature range of 0 to 70°C, the cable is suitable for controlled data center environments. With an MTBF rating of 1,000,000 hours, it provides long-term reliability for mission-critical infrastructure. Typical deployment scenarios include 400G switch breakout configurations, high-density interconnects within hyperscale data centers, and scalable cloud networking environments where efficient bandwidth distribution and low latency are critical.
Our 400G QSFP-DD to 2x200G QSFP-DD passive DAC cable is CE and RoHS certified and compliant with relevant industry standards. Each cable undergoes comprehensive quality assurance testing, including electrical validation, connector inspection, and EEPROM verification, ensuring consistent performance and reliability prior to deployment.
