1600Gb/s to 2x800Gb/s | OSFP to 2xOSFP | 2m | IHS to RHS

Product Overview

The NVIDIA MCA7K10 (MPN: 980-9IAO5-00X002) is an ultra-high-performance Active Copper Splitter Cable (ACC) designed for next-generation, large-scale AI clusters and high-performance computing (HPC) environments. Delivering a massive aggregate throughput of 1600Gb/s (1.6Tb/s), this premium 2-meter breakout cable splits a single, twin-port 1600Gb/s OSFP uplink into two independent 800Gb/s OSFP channels.

Utilizing advanced 8-channel 200G-PAM4 modulation, this active copper solution provides power-efficient, ultra-low-latency connectivity, acting as the ideal infrastructure bridge between high-density switches and next-gen network interface cards across extended rack distances.

Key Features

1.6Tb/s High-Density Breakout: Seamlessly splits a 1600Gb/s host link into twin 800Gb/s target channels to maximize switch port density and network configurability.
Extended 2-Meter Reach: Offers a longer 2m length for flexible cable management and cross-rack or multi-chassis deployments without compromising signal integrity.
Dual-Protocol Flexibility: Smart firmware automatically detects and supports both InfiniBand (XDR) and Ethernet protocols depending on the host switch configuration.
Optimized IHS-to-RHS Thermal Architecture: Designed with an Integrated Heat Sink (IHS / Closed Finned Top) on the 1600G switch side and a Riding Heat Sink (RHS / Flat Top) on the two 800G adapter ends for flawless thermal management.
Active Power Efficiency: Active signal conditioning ensures exceptional signal integrity over its 2-meter length while consuming significantly less power and cost than alternative optical transceiver setups.
