Kuwait DAC High-Speed ​​Cable QSFP-DD

QSFP-DD DAC cables in Kuwait provide high-speed, high-density connectivity for 200G, 400G, and 800G Ethernet and InfiniBand networks, supporting both passive and active configurations.

Overview

QSFP-DD (Quad Small Form-factor Pluggable Double Density) DAC cables are designed for high-performance data center interconnects, offering 8-channel electrical interfaces that double the lanes of traditional QSFP systems, enabling higher bandwidth within the same mechanical footprint . These cables are compatible with 25G/Lane NRZ and 50–112G/Lane PAM4 signaling, supporting aggregate data rates of 200G, 400G, and 800G .

Key Specifications

• Data Rates: Up to 400 Gbps for standard DACs, with some active variants supporting up to 800 Gbps .
• Channel Configuration: 8 channels per QSFP-DD port, each capable of 28Gbps NRZ or 50–56Gbps PAM4 .
• Compliance: IEEE 802.3bj, 802.3by, 802.3cd, InfiniBand EDR, SAS 3.0, and QSFP-DD MSA standards .
• Variants: Passive copper DACs for short-range, low-power connections; active DACs for longer reach and higher reliability .
• Breakout Options: QSFP-DD to multiple SFP56 or QSFP28 ports for flexible network topologies, including 400G to 8x50G or 400G to 4x100G configurations .
• EEPROM Support: Each QSFP-DD port includes an EEPROM for host system recognition and product information .

Advantages

• High Density: Supports more lanes in the same port space, ideal for modern high-density switches and servers .
• Low Latency: Passive DACs provide minimal latency, suitable for high-speed Ethernet backbones and AI workloads .
• Flexibility: Breakout cables allow splitting a single high-speed port into multiple lower-speed connections, enhancing network design options .
• Reliability: Advanced shielding and manufacturing processes reduce noise and improve signal integrity .

Applications

• Data Centers: High-speed interconnects between switches, servers, and storage units.
• AI and HPC Networks: Supports ultra-high throughput for AI training clusters and high-performance computing.
• Ethernet and InfiniBand Networks: Compatible with 200G, 400G, and 800G Ethernet and InfiniBand EDR systems . QSFP-DD DAC cables in Kuwait are available from multiple suppliers, including C-FLINK, Amphenol, Molex, and FS, offering both standard lengths and customizable options to meet specific deployment requirements . These cables provide a cost-effective, high-performance solution for modern data center and enterprise networking needs.
