NVIDIA MFS1S50-H010E 200G QSFP56 to 2x100G QSFP56 AOC, 10 m | Low Latency MMF

The NVIDIA MFS1S50 series is a family of QSFP56 VCSEL-based active optical splitter cables designed as cost-effective 200Gb/s to 2x100Gb/s interconnects for 200Gb/s InfiniBand HDR and 200GbE systems. The MFS1S50-H010E variant provides a 10-meter reach and connects a single 200Gb/s QSFP56 port on one side to two separate 100Gb/s QSFP56 connectors on the other — for example, a switch uplink to two servers.

The cable routes data signals from each of the four multimode fiber (MMF) pairs on the single QSFP56 end to the dual pair of each QSFP56 multiport end. Each QSFP56 end includes an EEPROM that provides product and status monitoring information readable by the host system. The cable is SFF-8665 compliant for the QSFP56 pluggable solution and supports the SFF-8636 I²C management interface.

NVIDIA cable solutions are designed for power-efficient data center interconnects, enabling higher port bandwidth, density, and configurability at reduced power requirements. Rigorous production testing supports out-of-the-box installation, performance, and durability.

• Programmable Rx output amplitude and pre-emphasis
• SFF-8665 compliant QSFP56 port
• Single 3.3V power supply
• 4.5 W typical power consumption at the 200G end
• Up to 30 m length available in the series; this variant is 10 m
• Hot pluggable
• RoHS compliant
• SFF-8636 compliant I²C management interface

The cable uses VCSEL (Vertical Cavity Surface-Emitting Laser) technology over multimode fiber. The 200Gb/s end transmits four lanes at 50Gb/s PAM4, and the splitter architecture maps these lanes to two 100Gb/s QSFP56 ends, each carrying two lanes. This allows a single high-density 200Gb/s switch port to serve two 100Gb/s endpoints without requiring separate 200G optics on each server side.

The AOC supports programmable Tx input equalization, programmable Rx output amplitude, and programmable Rx output pre-emphasis for physical layer link optimization. Tx/Rx CDR control is provided; CDR is enabled by default for 100GbE operation and can be disabled for 40G operation. Digital Diagnostic Monitoring (DDM) covers Rx optical power per lane, Tx optical power per lane, Tx bias current per lane, supply voltage, and transceiver case temperature, with warning and alarm thresholds.

Rate select is supported via registers 0x57–0x58. Two bits are assigned per receiver lane in byte 0x57 and two bits per transmitter lane in byte 0x58 to specify up to four bitrates per SFF-8636 Rev 2.9.2 Table 6-5 XN_RATE_SELECT ENCODINGS. All four lanes must use the same rate select value.

The MFS1S50-H010E is designed for QSFP56 ports supporting 200Gb/s InfiniBand HDR and 200GbE. The 200Gb/s end connects to a single QSFP56 port; the 100Gb/s ends connect to two QSFP56 ports operating at 100Gb/s. It is SFF-8665 and SFF-8636 compliant. For non-NVIDIA hosts, compatibility and breakout support should be confirmed before ordering.

The MFS1S50 series is available in multiple lengths from 3 m to 30 m. The table below lists the ordering part numbers from the product specification to help select the correct reach.

Note: The ordering table in the product specification lists 10 m as MFS1S50-H010V. This page covers the MFS1S50-H010E designation; please confirm the exact part number suffix with sales before ordering.
