Product Description
00G QSFP-DD Passive Direct Attach Copper Cable (DAC) for Data Center Networking & High-Performance Computing
 
Description QSFP-DD (Quad Small Form-factor Pluggable Double Density) passive copper direct-attach cables provide a cost-efficient solution for establishing 400-Gigabit connections between QSFP-DD ports in data center environments. Designed exclusively for short-reach deployments, these cables offer high-density connectivity and exceptional performance within strict distance limits. Compliant with industry-standard protocols, they ensure seamless integration into high-speed networking infrastructures, ideal for space-constrained racks and low-latency applications.
 
 
Key Features
●Compliant with QSFP-DD MSA Specifications
●Full Compliance with IEEE 802.3cd (400GBASE-CR4/CR8) and InfiniBand HDR
●Total Bandwidth: 400 Gb/s (8x50Gbps PAM4 lanes)
●8 Independent Duplex Channels operating at 50Gbps (Supports Data Rates up to 100Gbps)
●100Ω Differential Impedance System
●Single 3.3V Power Supply, Ultra-Low Power Consumption: <3.5W
●Operating Temperature Range: -40°C to 85°C (Industrial Grade)
●All-Metal Housing with Enhanced EMI Shielding
●Advanced Signal Integrity Design with minimal pair-to-pair skew
●AC-Coupled LVDS Signals for Noise Immunity
●Integrated EEPROM for cable diagnostics & link management
●Cable AWG Range: 28 AWG to 24 AWG (Optimized for ≤3-meter performance)
●RoHS-Compliant Materials for environmental safety
 
 
Applications
 
●Data Centers: Server-to-Switch Links, Top-of-Rack (TOR) Connections
●High-Performance Computing (HPC): Intra-rack Cluster Networking
●Edge Computing: Ultra-Dense Switch Interconnects
●Telecommunications: Short-Haul Aggregation Layers
 
Industry Standards Compliance
●IEEE 802.3cd (400GBASE-CR4/CR8)
●InfiniBand HDR (High Data Rate)
●QSFP-DD Multi-Source Agreement (MSA)
