  • Hot-pluggable with 3.3 V supply and two-wire serial management
  • SFF-8665 compliant standard QSFP56 electrical connector

NVIDIA HDR InfiniBand Transceiver

The MMS1W50-HM is a QSFP56 transceiver built for NVIDIA HDR InfiniBand clusters. It delivers up to 200 Gb/s over single-mode fibre using a 1310 nm FR4 optical interface. The module is certified for end-to-end compliance in NVIDIA HDR systems.

Suits HDR clusters, not other speeds

This transceiver fits builders expanding or repairing NVIDIA HDR InfiniBand fabrics that require FR4 optics. It is not for environments running lower-speed EDR or FDR links, nor for Ethernet-only switches that do not support the HDR InfiniBand protocol.

200 Gb/s FR4 over LC duplex

The decisive specification is the 200 Gb/s FR4 rating over LC duplex connectors at 1310 nm. The module uses a standard QSFP56 electrical interface with a 3.3 V supply and SFF-8665 compliance for hot-plug management.

Questions about this item

What speed does the QSFP56 interface on the MMS1W50-HM support in practice?

The QSFP56 interface is rated for up to 200Gb/s operation in NVIDIA HDR InfiniBand systems.

What physical connectors and form factor does the MMS1W50-HM need to fit?

It uses a standard QSFP56 module with dual LC optical connectors for single-mode fibre.

How is the MMS1W50-HM installed, and what step is often missed?

Insert the hot-pluggable module into the QSFP56 cage until it clicks, then connect the LC duplex patch cord; the module draws power from the host 3.3V supply.
