MFS1S50-H040V, Mellanox Active Optical Cable, 200Gb/s, 2x100Gb/s IB HDR, QSFP56 to 2x QSFP56, 40m

The Mellanox MFS1S50-H040V is a high-performance InfiniBand HDR active optical cable (AOC) designed as a data center connectivity accessory for modern HPC clusters and cloud infrastructures. It delivers a 200Gb/s to 2x 100Gb/s InfiniBand HDR breakout link over 40 m of multi-mode fiber, giving reliable high bandwidth and low latency between switches, servers, and storage nodes. With QSFP56 to 2x QSFP56 interfaces and QSFP56 male connectors on all ends, the MFS1S50-H040V fits smoothly into existing HDR InfiniBand environments across Asia, Europe, Africa, and North America.

This AOC is ideal for distributors and small to mid-size system integrators who need a simple, pre-terminated solution to build scale-out fabrics without complex fiber planning. For end users, it reduces deployment time because there is no need for separate transceivers and patch cords. The factory-terminated design offers consistent optical performance, helping maintain stable throughput for data-intensive workloads such as AI training, real-time analytics, and research computing.

The 1 x 200G (4x 50G PAM4) to 2 x 100G (2x 50G PAM4 each) breakout configuration allows you to connect a 200G HDR switch port to two 100G HDR endpoints, optimizing port utilization in dense leaf-spine or fat-tree architectures. This improves return on investment by maximizing switch capacity while keeping cabling simple and tidy. The 40 m reach supports typical top-of-rack to aggregation or spine connections inside large data halls, enabling flexible rack layouts without signal repeaters.

As a Mellanox InfiniBand HDR interconnect accessory, the MFS1S50-H040V is built for continuous 24/7 operation in demanding environments. Its active optical cable assembly with multi-mode fiber offers lower weight and better cable management than comparable copper solutions, especially over longer distances. This helps maintain airflow and simplifies future expansion. Whether you are upgrading an existing InfiniBand HDR fabric or designing a new high-speed cluster, the MFS1S50-H040V provides a reliable, plug-and-play option that aligns with global data center standards and best practices.
