NVIDIA mellanox MFS1S00-H020V 200Gb/s QSFP56 Active Optical Cable 20m AOC for HDR InfiniBand

Medium-reach 20-meter active optical cable featuring VCSEL technology—delivering 200Gb/s throughput over multimode fiber for HDR InfiniBand and 200GbE data center interconnects with integrated digital diagnostics and low power consumption.

• 200Gb/s aggregate bandwidth over 4x 50Gb/s PAM4 lanes per end
• 20-meter length with 3.0mm diameter, LSZH-rated duplex fiber jacket
• Supports InfiniBand HDR (200Gb/s) and 200 Gigabit Ethernet
• Full Digital Diagnostic Monitoring (DDM): optical power, temperature, voltage, bias current
• Hot-pluggable QSFP56 form factor, SFF-8665 compliant, 5.0W typical power per end

• 200Gb/s Throughput: Four 50Gb/s PAM4 channels per direction, aggregate 200Gb/s full duplex.
• VCSEL Technology: Vertical Cavity Surface-Emitting Lasers for reliable, low-cost multimode transmission over 20m.
• Retiming Capability: Selectable retiming on all lanes up to 50Gb/s for optimal signal conditioning.
• Digital Diagnostic Monitoring (DDM): Real-time monitoring of optical power, temperature, voltage, and bias current for proactive maintenance.
• Programmable Equalization: Tx input equalization and Rx output pre-emphasis for link optimization.

The MFS1S00-H020V complies with SFF-8665 (QSFP56 electrical) and SFF-8636 (management interface). It uses 4x 50Gb/s PAM4 modulation over multimode fiber (OM3/OM4). Supports InfiniBand HDR (IBTA 1.5) and 200GBASE-SR4 Ethernet. Integrated CDR (Clock and Data Recovery) per lane with rate select for 25.78125 GBd NRZ (EDR) or 26.5625 GBd PAM4 (HDR). RoHS compliant.

The MFS1S00-H020V converts electrical 50Gb/s PAM4 signals from the host into optical signals using four VCSEL lasers at one end. These signals travel over multimode fiber and are converted back to electrical by photodetectors at the far end. The integrated retiming function reconditions the signal using CDR circuits, reducing jitter and extending reach. Digital diagnostics continuously monitor link health, providing real-time feedback via I²C interface for link optimization and fault prediction.

• InfiniBand HDR Fabrics: Connect QM8700/QM8790 switches to ConnectX-6/7 adapters across multiple racks.
• 200GbE Networks: Link Spectrum SN3700/SN4600 switches for high-bandwidth Ethernet up to 20m.
• Top-of-Rack to Adjacent Rack: Medium-reach connections between neighboring racks.
• Storage Clusters: RDMA over Converged Ethernet (RoCE) and NVMe-oF deployments requiring longer reach.

Note: Operating temperature 0°C to 70°C, storage -40°C to 85°C. Minimum bend radius 30mm. Supports up to 100m reach with longer lengths (H050V, H100V). Length tolerance: ±0.5m for 20m length.

• vs. Passive Copper: Longer reach (20m) with lower weight, better airflow, and complete EMI immunity.
• vs. Active Copper (ACC): Optical solution provides galvanic isolation and extended distance capability.
• Integrated Retiming: Improves signal quality and jitter performance over standard AOCs at 20m distance.
• Full DDM Support: Real-time optical power and temperature monitoring for proactive maintenance and fault prediction.
• Medium-Reach Flexibility: Ideal for connections between adjacent racks or across aisles.

We offer 24/7 technical consultation, RMA services, and cabling infrastructure design support. Each MFS1S00-H020V is backed by a 1-year warranty and 100% factory testing. Custom lengths available for volume orders. Our inventory ensures same-day dispatch for in-stock items. Pre-sales support for transceiver compatibility verification and link budget calculation is available.

A: Yes, it is fully compatible with ConnectX-6 (HDR) and ConnectX-5 (EDR) adapters. The 20m reach is well within the optical budget for HDR.

A: Yes, it supports 100GbE by operating in 2x50G PAM4 mode or 4x25G NRZ mode with appropriate rate select settings.

A: Power consumption is 5.0W per end typical, independent of length due to integrated retiming and VCSEL drivers.

A: No, it is plug-and-play. The cable auto-negotiates protocol and speed with the host.

A: The minimum bend radius is 30mm. Avoid sharp bends to maintain signal integrity.

• ESD Sensitivity: Use grounded wrist straps when inserting into QSFP cages. Connectors are shipped with protective caps—remove only immediately before installation.
• Clean Before Use: Always clean optical connectors with appropriate one-click cleaners before insertion—contamination causes link errors.
• Bend Radius: Do not exceed 30mm bend radius; avoid tension on connectors.
• Operating Temperature: Ensure ambient temperature within 0°C–70°C.
• Storage: Store in clean, dry environment between -40°C and 85°C.
