Mellanox MCA4J80-N004 Compatible 800G Twin-port OSFP Direct Attach Cable
Overview:
The NVIDIA Mellanox MCA4J80-N004 is a high-performance **800G Twin-port OSFP Active Direct Attach Cable (ACC)**. As an active copper cable, it is designed for extended reach up to 4m, providing a cost-effective and low-latency solution for high-speed interconnects. This cable is an essential component for modern data centers and high-performance computing (HPC) environments, enabling robust **800Gbps** connectivity. It provides a reliable and energy-efficient alternative to optical fiber for short to medium-distance connections, making it ideal for linking switches within a rack or between adjacent racks. This Direct Attach Cable is a crucial enabler for building next-generation InfiniBand and Ethernet networks.
Expanded Overview:
The NVIDIA Mellanox MCA4J80-N004 is built on the **OSFP (Octal Small Form Factor Pluggable)** form factor, which provides a compact and hot-pluggable solution. The “active” designation means it contains an integrated equalizer circuit in each end, which boosts the signal and allows for longer cable lengths compared to passive DACs, while maintaining very low latency and power consumption (1.5 Watts per end). The cable supports both InfiniBand and Ethernet protocols, automatically adapting based on the connected device. Its **twin-port** design is ideal for linking two high-speed devices like NVIDIA’s Quantum-2 switches or connecting to systems like the DGX-H100. The **finned top** of the OSFP connector ensures superior thermal management, contributing to stable performance under demanding conditions. This Direct Attach Cable is a reliable and powerful choice for any enterprise-level application.
