Boosting Data Rates with PAM4 Modulation
PAM4 modulation plays a critical role in advancing high-speed data transmission by encoding two bits per symbol through four distinct signal levels. This method effectively doubles the data rate compared to conventional NRZ signaling, without requiring additional bandwidth—making it an efficient solution for 400G Ethernet and future standards.
By conveying more data within the same spectral range, PAM4 increases spectral efficiency and minimizes the need for extra optical components. This results in significant cost savings and improved energy efficiency for high-performance networks.
Powering Scalable, High-Efficiency Networks with OSFP Cables
OSFP high-speed cables are a critical enabler for scalable and efficient connectivity in modern data centers. Their compact design supports greater port density, maximizing valuable rack space. When coupled with PAM4 signaling, they ensure reliable signal integrity over longer distances, minimizing dependence on active components.
Paired with a robust, user-friendly mechanical design, KEXINT OSFP cable assemblies deliver a future-proof solution for data centers demanding high bandwidth and adaptive flexibility.
OSFP DAC Cables for High-Performance 400G Connections
This configuration establishes a high-speed, low-latency 400G link between two GPU servers, each equipped with an NVIDIA® ConnectX-7 NIC. Using a high-performance OSFP-to-OSFP Direct Attach Copper cable (DAC) available in lengths from 0.5 to 2 meters—the setup delivers the ultra-high bandwidth and minimal latency required for intensive AI workloads and high-performance computing (HPC) in dense data center environments.
Building 800G Clusters for Quantum-2 InfiniBand with OSFP Cabling
To address the extreme bandwidth requirements of modern HPC and AI clusters, there is a suite of purpose-built 800G OSFP interconnect solutions optimized for NVIDIA Quantum-2 InfiniBand switches. Our cabling ensures seamless, low-latency 800G connectivity, whether for intra-rack or inter-row deployments.
For high-density, cost-and-power-sensitive connections up to 3 meters, our Direct Attach Copper (DAC) cables deliver maximum efficiency. For extended reaches of 20 meters and beyond without signal degradation, our Active Optical Cables (AOC) offer a robust alternative. Both solutions feature full compatibility with twin-port OSFP interfaces, enabling plug-and-play scalability for accelerated, large-scale infrastructure.
Ultra-High-Density 1.6T Interconnect for Short-Reach Applications
The OSFP-1.6T cable provides a high-performance, short-reach interconnect solution for direct switch-to-switch connections, supporting distances from 0.5 to 1 meter. It delivers aggregate throughput up to 1600 Gbps and features a closed-top design engineered for reliable operation in liquid-cooled environments. This makes it an ideal choice for building ultra-high-bandwidth links within dense, high-performance computing and machine learning architectures.
