South African OEMDAC High-Speed ​​Cable 200G

The 200G High-Speed DAC (Direct Attach Cable) is a short-range, high-performance Ethernet solution designed for data centers, supporting QSFP56 or OSFP form factors with PAM4 modulation for 56Gbps per channel.

Overview

The 200G DAC is primarily used for short-distance interconnects within data centers, typically up to 3 meters, connecting 200G server network cards, switches, or AI systems. It provides high throughput, low latency, and energy-efficient operation, making it ideal for high-performance computing, RoCE applications, and dense networking environments (NADDOD).

Technical Specifications

Form Factor: QSFP56 (Quad Small Form Factor Pluggable 56) or OSFP (Octal Small Form Factor Pluggable) Modulation: PAM4, supporting 56Gbps per channel, with four channels combining to 200Gbps aggregate Cable Type: Passive DAC or Active Optical Cable (AOC) depending on distance and application Distance: Typically up to 3 meters for DAC; longer distances may require AOC Compatibility: Tested with major switches and NICs, including Arista 7060X6, NVIDIA Spectrum-4 SN5000, Cisco Nexus 9300-GX2, and Broadcom BCM957608 Power and Signal Integrity: Low power consumption, low crosstalk, and high reliability for dense rack environments ApplicationsData Centers: High-speed interconnects between servers and switchesAI and HPC Networks: Short-range connections for GPU clusters or DGX systemsCloud Computing: High-density, low-latency intra-rack connectionsRoCE (RDMA over Converged Ethernet): Optimized for low-latency, high-throughput workloads Suppliers and Availability in South AfricaWhile specific South African OEMDAC brands are not listed, Lapp Southern Africa is a leading supplier of high-performance cabling solutions and may provide access to compatible 200G DAC or AOC cables.

International manufacturers like Siemon, Amphenol, TE Connectivity, and NADDOD offer factory-tested 200G DACs that can be sourced through local distributors or import channels.

Summary

The 200G High-Speed DAC is a short-range, high-bandwidth solution for modern data centers, supporting QSFP56 or OSFP form factors with PAM4 modulation. It ensures reliable, low-latency connections for servers, switches, and AI systems, and is compatible with major networking equipment. For South African deployment, suppliers like Lapp Southern Africa can provide access to these high-performance cables, either directly or via international partners.
