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.
