What is the total bandwidth provided by the NVIDIA MMS4X00-NS-FLT transceiver?

The NVIDIA MMS4X00-NS-FLT delivers an aggregate data rate of 800Gbps. It is categorized as an 800Gbps 2x400G twin-port OSFP optical transceiver, meaning the total bandwidth is presented through two 400G interfaces. This makes it suitable for high-capacity links in data center and backbone network designs that target 800Gbps-class connectivity.

How is the 800Gbps capacity of MMS4X00-NS-FLT presented at the port level?

The module is specified as an 800Gbps 2x400G twin-port OSFP optical transceiver. This means its 800Gbps capacity is provided as two separate 400G ports. Each 400G interface can be used as an independent single-mode optical link, supporting architectures that rely on 400G connections while still benefiting from an 800Gbps-capable hardware platform.

Which form factor and fiber type does MMS4X00-NS-FLT use?

MMS4X00-NS-FLT is an OSFP optical transceiver designed for single-mode applications and identified as a flat-top variant. The OSFP form factor ensures compatibility with OSFP cages on supported networking platforms, while the single-mode designation aligns it with single-mode fiber plants. The flat-top description refers to its specific mechanical profile for OSFP slots.

Is the NVIDIA MMS4X00-NS-FLT suitable for single-mode fiber deployments?

Yes, according to its categorization, the MMS4X00-NS-FLT is an 800Gbps 2x400G twin-port, single-mode OSFP optical transceiver. This means it is intended for use with single-mode fiber infrastructure, making it appropriate for data center and network environments that standardize on single-mode cabling for high-speed optical links.

What distinguishes the MMS4X00-NS-FLT from other OSFP modules?

MMS4X00-NS-FLT is characterized as an 800Gbps 2x400G twin-port, single-mode, flat-top OSFP optical transceiver. The combination of 2x400G twin-port configuration, single-mode operation, and flat-top mechanical profile differentiates it from other OSFP modules that may use different port configurations, fiber types, or mechanical variants.

Product overview

The NVIDIA MMS4X00-NS-FLT is an 800Gbps 2x400G twin-port OSFP optical transceiver designed for high-bandwidth single-mode networks in a flat-top form factor. As part of the OSFP optical transceiver family, it is intended for deployments that require 800Gbps connectivity presented as two 400G interfaces. The single-mode design aligns with modern data center and backbone architectures that standardize on single-mode fiber for predictable performance. The twin-port 2x400G layout supports architectures that logically segment or aggregate 400G links within 800Gbps-capable platforms. Classified as a flat-top variant, MMS4X00-NS-FLT is suited to environments where this specific mechanical profile is required for chassis or thermal design. With its combination of 800Gbps aggregate throughput, 2x400G twin-port configuration, OSFP form factor, single-mode fiber support, and flat-top mechanical design, this transceiver fits demanding high-speed optical interconnect needs.
