COMNEN’s 1.6T OSFP Passive Direct Attach Copper (DAC) cables are the industry’s answer to the 224G-per-lane challenge. Specifically engineered for the most demanding AI and Machine Learning (ML) environments, these cables provide a massive 1.6 Terabit aggregate bandwidth, enabling the seamless data flow required for the next generation of GPU-to-Switch and Switch-to-Switch interconnects. By leveraging advanced material science and high-precision manufacturing, our 1.6T OSFP DACs overcome the aggressive signal attenuation inherent at such high frequencies. With a focus on Signal Integrity (SI) and thermal efficiency, these cables are the primary choice for data center architects deploying NVIDIA Blackwell or 800G/1.6T Leaf-Spine architectures who require the lowest possible latency and power consumption. Specifications Compatible NVIDIA(ETH) / Arista / Generic Vendor Name COMNEN Max Data Rate 1600G Form Factor OSFP to OSFP Wire AWG 25AWG Conductor Copper Cable Type Passive Twinax Minimum Bend Radius 30mm Temperature Range 0 to 70°C (32 to 158°F) Jacket Material PET Modulation Format PAM4 Protocols OSFP MSA, IEEE 802.3ck, CMIS v5.0 Power Consumption ≤0.1W Cable Length 0.3m~1m Power Supply 3.3V Application 1.6T Ethernet, IB NDR, Compliant RoHS Warranty 5 Years Features 224G-per-Lane Architecture: Master 1.6T Signal Integrity The transition to 1.6T Ethernet marks the industry’s shift to 224.25Gbps per lane signaling. At these extreme frequencies, traditional copper materials face severe Insertion Loss (IL) and electromagnetic interference. COMNEN’s 1.6T OSFP Passive DACs are engineered to overcome the “224G Barrier” through: Ultra-Low Loss Dielectrics: Utilizing advanced skin-effect-optimized silver-plated copper to minimize signal attenuation. Precision Impedance Matching: Every cable is tuned to 100 ± 3 Ohms at the paddle card transition to eliminate signal reflections that can crash 1.6T links. Automated Laser-Stripping: By eliminating human error in shielding removal, we maintain perfect symmetry across all 8 lanes, ensuring a Pre-FEC BER < 1E-15. IEEE 802.3dj & OSFP MSA Compliance: The 1.6T Standard In the rapidly evolving 1.6T landscape, interoperability is non-negotiable. Our cables are designed and tested to meet the latest IEEE 802.3dj (Standard for 200 Gb/s, 400 Gb/s, 800 Gb/s, and 1.6 Tb/s Operation) draft specifications. OSFP 1600 Support: Fully compliant with the latest OSFP MSA (Multi-Source Agreement) physical dimensions and management interfaces (CMIS). Backward Compatibility: While optimized for 1.6T, the OSFP form factor ensures structural alignment with existing OSFP800 and OSFP400 infrastructure where required. Future-Proof Validation: We use 110GHz Vector Network Analyzers (VNA) to validate that every cable exceeds the frequency requirements of the 802.3dj standard, guaranteeing performance in next-gen high-radix switches. Optimized for AI Clusters: Built for NVIDIA Blackwell & B200 Systems The 1.6T OSFP DAC is the critical backbone for the next generation of AI Superchips. Specifically optimized for the NVIDIA Blackwell (B100/B200) architecture and high-performance InfiniBand/Ethernet switches, COMNEN 1.6T cables provide the ultra-high bandwidth required for Large Language Model (LLM) training. Maximum GPU Throughput: Supports the massive “East-West” traffic generated in Blackwell-based DGX/HGX clusters. 0-Watt Efficiency: Unlike 1.6T optical modules that can pull up to 25W per port, our passive DACs consume 0W, preserving your rack’s thermal budget for high-TDP GPUs. Short-Reach Precision: Available in 0.3m, 0.5m, and 1m lengths, perfect for high-density Spine-Leaf and ToR (Top-of-Rack) configurations where every nanosecond of latency counts.
