WHY CHOOSE THIS PRODUCT?

• MMS4X00-NM is a strong fit when a deployment needs two 400G links from a single OSFP position, 500m single-mode reach and compatibility with NVIDIA Quantum-2 or Spectrum-4 infrastructure. Compared with the 100m MMS4X00-NS, its longer tested reach provides greater data-center deployment flexibility, while the twin-port design improves high-density 400G connectivity. For procurement teams, the key checks are OSFP compatibility, required MPO-12/APC cabling, switch platform support and the 500m link requirement before purchase.
