NVIDIA Technologies MMS1V70-CM Mellanox 100GbE QSFP28 Optical Transceiver Module

The NVIDIA Technologies MMS1V70-CM Mellanox 100GbE QSFP28 optical transceiver module is designed to enable high-speed connectivity over single mode fiber for data centers and enterprise networks. This transceiver supports a single 1-lane (DR1) QSFP28 form factor, allowing seamless integration into Mellanox Ethernet switches such as MSN2700 and MSN4700. It converts four 25Gb/s NRZ electrical channels into a single 100Gb/s PAM4 optical signal, facilitating efficient data transmission over distances up to 500 meters. The module operates at a nominal wavelength of 1310nm, making it suitable for long-reach applications and legacy 100GbE systems while supporting the emerging 400GbE PAM4 standards. Its robust design and rigorous manufacturing testing ensure reliable performance and durability out of the box.

Equipped with features like programmable receive (Rx) output amplitude and pre-emphasis, the MMS1V70-CM allows for customized signal optimization to match specific network requirements. It complies with industry standards including the QSFP28 MSA, IEEE 802.3bm CAUI-4, and SFF-8665, ensuring broad compatibility with modern data infrastructure. The module is hot-pluggable and powered by a single 3.3V supply, with an ultra-low power dissipation of approximately 0 watts at each end when retimed, supporting energy-efficient deployments. Its environmental friendliness is affirmed through RoHS compliance, making it suitable for sustainable data center operations.

Management and diagnostics are facilitated via the SFF-8636 compliant I2C interface, providing real-time health monitoring and configuration options. Designed for ease of installation, this transceiver is compatible with NVIDIA’s suite of Mellanox switches and network equipment, delivering high performance with minimal maintenance. Its compact, hot-pluggable form factor simplifies deployment and replacement, reducing network downtime. Whether expanding existing 100GbE links or converging with emerging 400GbE architectures, the NVIDIA MMS1V70-CM offers a reliable, high-speed optical solution tailored for modern networking environments.
