NVIDIA 2x100G to 2x 100G (2x50G-PAM4) OSFP to 2xQSFP56 AOC Cable (5m)

Overview

The NVIDIA MFA7U40-H005 is a 5-meter active optical cable designed to connect one OSFP port to two QSFP56 ports, delivering up to 200 Gbit/s of total throughput. It uses two independent 100 Gbit/s channels with 50G PAM4 signaling to support high-bandwidth workloads in data centers and high-performance computing clusters. The cable’s fiber optic construction ensures signal integrity over the full 16.4-foot length while remaining lightweight and flexible for easy routing in dense rack environments.

Key features

• Active optical technology regenerates signals to maintain consistent quality across the full cable length
• Dual 100 Gbit/s channels enable efficient splitting of a 200 Gbit/s OSFP connection into two QSFP56 ports
• Flexible jacket design allows smooth routing through crowded racks and overhead trays without adding strain
• Immunity to electromagnetic interference reduces noise and improves overall network reliability
• HDR support ensures compatibility with modern NVIDIA networking equipment and other high data rate fabrics
• Plug-and-play operation eliminates the need for additional transceivers, cleaning kits, or special tools
