NVIDIA Mellanox® MFS1S50-H020V 200Gb to 2x100Gb AOC: This extended-reach active optical splitter cable (AOC) is engineered to bridge significant distances in hyperscale InfiniBand HDR environments. It splits a single 200Gb/s QSFP56 switch port into two 100Gb/s (HDR100) endpoints up to 20 meters away. Utilizing high-efficiency VCSEL technology, it overcomes the physical limitations of copper to deliver pristine signal integrity across rows or zones. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.
🔧 Technical Specifications
OEM: NVIDIA / Mellanox
P/N: MFS1S50-H020V
Form Factor: QSFP56 (200G) to 2x QSFP56 (100G)
Data Rate: 200Gb/s to 2x 100Gb/s (HDR to 2x HDR100)
Length: 20 Meters
Power Consumption: < 5.0W (Source) / < 3.5W (Endpoints)
🌐 Engineering Context: The MFS1S50-H020V is critical for "End-of-Row" (EoR) or "Middle-of-Row" (MoR) architectures where compute nodes are physically distant from the aggregation layer. Compared to equivalent copper solutions (which fail beyond 3m) or transceivers (which add complexity and cost), this AOC offers a "plug-and-play" solution with Deterministic Latency and complete EMI Immunity. It allows for flexible floor planning, enabling non-adjacent racks to participate in the same high-speed HDR fabric.
🧠 Typical Use Cases
Connecting central NVIDIA Quantum HDR switches to servers located in distant racks (up to 20m away).
Creating large-scale "Dragonfly" or "Fat Tree" topologies spanning multiple rows.
Connecting GPU clusters to storage appliances located in separate cooling zones.
Simplifying cable management in overhead trays by reducing bulk compared to copper bundles.
 
✅ Compatible With: NVIDIA Quantum HDR Switches (QM8700/QM8790), Spectrum-2/3 Ethernet Switches, ConnectX-6 HDR100 Network Adapters, and BlueField-2/3 DPUs. (Requires ports configured for native 200Gb HDR/200GbE operation and MSA-compliant support)
❌ NOT Compatible With: Standard 100G EDR (NRZ) ports without PAM4 capability; 40G QSFP+ legacy hardware; systems unable to support 5W power draw on QSFP ports.
 
🛠️ Installation & Thermal Management
Slack Storage: 20 meters creates significant cable slack. Use "figure-8" looping techniques in overhead trays or vertical managers to prevent fiber stress. Do not coil tightly (minimum bend radius 60mm).
Airflow: The thin active fiber profile improves airflow efficiency in high-density racks compared to bulky copper bundles, reducing static pressure on server fans.
Connector Care: Active cables contain delicate optics. Keep dust caps on until the exact moment of insertion to prevent contamination of the lenses.
