Addon MFS4R12CB-020-AO

Mellanox® MFS4R12CB-020 Compatible TAA Compliant 40GBase-AOC QSFP+ Active Optical Cable (850nm, MMF, 20m)

The AddonMFS4R12CB-020-AO is a high-performance 40GBase Active Optical Cable(AOC) that delivers fast, stable data  connectivity across a 20-meter (65.6 ft) multimode fiber link. Built as a direct replacement for Mellanox® MFS4R12CB-020, this QSFP+ cable is ideal for data center interconnects, high-performance computing (HPC), and enterprise networks that demand consistent 40 Gbps throughput with minimal latency. Operating at an 850 nm wavelength, it ensures superior signal integrity, zero EMI interference, and greater reliability in high-density environments. With TAA compliance, plug-and-play installation, and a limited lifetime warranty, this AddonAOC provides cost-effective performance at scale.

Features

The AddonMFS4R12CB-020-AO provides the high-speed networking capability needed for modern IT infrastructure. It supports 40GBase-AOC standards with a QSFP+ form factor and is specifically engineered for compatibility with Mellanox® MFS4R12CB-020 transceivers. This Active Optical Cablesupports multimode fiber transmission over 20 meters, enabling low-latency communication between switches, servers, and storage arrays in performance-sensitive environments.Its 850 nm wavelength and multimode fiber construction ensure excellent resistance to signal degradation and electromagnetic interference (EMI), making it the ideal choice for use in dense data center racks or electrically noisy zones. Each cable is individually serialized and tested to meet rigorous performance and compatibility benchmarks, ensuring consistent and reliable operation.

Advanced Options

Whether you're upgrading network links, building a scalable cluster, or meeting regulated procurement requirements, this TAA-compliant AOC offers the flexibility and dependability required for long-term deployment. It is hot-swappable and designed for plug-and-play deployment, reducing downtime and simplifying installation across a variety of systems.The AddonMFS4R12CB-020-AO is engineered to provide consistent and high-performance connectivity in mission-critical networking environments. It features active optical components designed to minimize signal degradation over extended distances, while delivering EMI immunity that copper cables cannot match—particularly valuable in high-density rack and server environments.
