What is the difference between this and a standard 100G cable?

This is a splitter cable that takes a 200G HDR port and splits it into two 100G HDR100 ports. Standard 100G cables are point-to-point and typically use EDR (NRZ) technology, whereas this uses HDR (PAM4) technology.

Is the MFS1S50-H005E LSZH rated?

Yes, this cable features a Low Smoke Zero Halogen (LSZH) jacket, making it suitable for data centers with strict environmental and fire safety regulations.

Can I use this for Ethernet?

While designed for InfiniBand HDR, this cable is based on the QSFP56 standard and can be used in 200GbE environments that support the split 2x100G configuration.

NVIDIA Mellanox® MFS1S50-H005E 200Gb to 2x100Gb AOC: This active optical splitter cable (AOC) provides a high-efficiency link between a single 200Gb/s InfiniBand HDR port and two 100Gb/s HDR100 endpoints. Utilizing VCSEL technology over multi-mode fiber (MMF), it is engineered for distances where passive copper is no longer viable. This is a fixed-length integrated cable assembly, not a transceiver with a detachable patch cord.

🔧 Technical Specifications

OEM: NVIDIA / Mellanox
P/N: MFS1S50-H005E
Type: Active Optical Splitter (Breakout)
Data Rate: 200Gb/s to 2x 100Gb/s (HDR to 2x HDR100)
Cable Jacket: Low Smoke Zero Halogen (LSZH)
Length: 5 Meters
Power Consumption: < 5.0W (Source) / < 3.5W (Endpoint)

🌐 Engineering Context: The MFS1S50-H005E is the industry standard for doubling switch port density in InfiniBand HDR fabrics. Compared to equivalent copper solutions, AOC offers lower weight, tighter bend radius, and superior long-term signal stability. The 5-meter reach is ideal for larger rack-to-rack deployments where Deterministic Latency and EMI Immunity are mandatory for HPC and AI computational workloads.

🧠 Typical Use Cases

Splitting a 200G HDR Switch port to connect two ConnectX-6 HDR100 adapters.
Expanding port density in NVIDIA Quantum HDR switch fabrics.
Deployment in safety-critical environments requiring Low Smoke Zero Halogen (LSZH) compliance.
Optimizing airflow in high-density AI clusters by replacing bulky copper DACs.

✅ Compatible With: NVIDIA Quantum HDR Switches (QM8700/QM8790), ConnectX-6 HDR/HDR100 NICs, and BlueField-2 DPUs. (Requires ports configured for native 200Gb HDR operation and MSA-compliant support)

❌ NOT Compatible With: Standard 100G EDR InfiniBand ports without PAM4 support; standard Ethernet-only switches not licensed for HDR; 40G/56G legacy hardware.

🛠️ Installation & Thermal Management

LSZH Safety: The LSZH jacket ensures that in the event of high heat, smoke emission is minimal and non-toxic, meeting European and high-tier data center fire safety standards.
Port Mapping: The host system must be configured to recognize the 200G port in "Split Mode" (2x100G) to ensure the 4x50G PAM4 lanes are correctly routed to the dual 2-lane QSFP56 ends.
Handling: The internal fiber pairs are optimized for a 5m span; ensure the cable is not cinched tightly with plastic zip ties, which can cause micro-bends and packet loss.
