400G PAM4 QSFP-DD to 4x100G QSFP56 PAM4 DAC Cable 3MProduct Overview:The 400G PAM4 QSFP-DD to 4x100G QSFP56 PAM4 DAC Cable is a premium networking solution designed for ultra-high-speed data transmission in modern data centers and networking environments. This cable utilizes the PAM4 modulation technique to effectively distribute a 400Gbps QSFP-DD signal into four separate 100Gbps QSFP56 channels.

Key Features:

1. Advanced PAM4 Signaling: Employs Pulse Amplitude Modulation (PAM4) technology, which doubles the data rate transmission by sending two bits of data in each signal change, enhancing overall bandwidth efficiency.
2. High-Density Configuration: Facilitates the conversion of a single 400Gbps QSFP-DD interface to four individual 100Gbps QSFP56 ports, optimizing port usage and infrastructure scalability.
3. Direct Attach Copper Design: Utilizes robust and reliable copper cabling, ensuring stable and secure data transfer without the need for active electronic components.
4. Energy-Efficient Solution: Offers a more power-saving alternative compared to optical solutions, reducing operational costs in data centers.
5. Plug-and-Play Operation: Designed for straightforward deployment without complex configuration, offering ease of use and minimal installation time.
6. Compatibility and Interoperability: Adheres to industry standards, ensuring compatibility with a wide range of networking equipment that supports QSFP-DD and QSFP56 interfaces.

Applications:

• Ideal for high-performance computing centers, cloud storage, and large-scale data centers requiring high-speed data transfer.
• Suitable for aggregating multiple 100Gbps links into a single 400Gbps connection, streamlining network infrastructure.
• Used in network backbones, metro networks, and as part of the interconnects in hyper-scale data centers.

Specifications:
