Nvidia, Cisco, and Partners Launch New Pluggable Optics for AI Data Centers

Nvidia, Cisco, TE Connectivity, and Amphenol have introduced a new pluggable optics form factor tailored for AI data centers. This innovation aims to enhance the efficiency and flexibility of data transmission within these centers.

Pluggable optics are small modules that fit into network switches, converting electrical signals into light for data travel across fiber connections between servers. Cisco has been expanding its offerings with advanced modules such as the 1.6T OSFP and 800G Linear Pluggable Optics (LPO), which significantly reduce power consumption.

Notably, Cisco's LPO solutions cut power usage by approximately 50% for the optical modules and around 30% overall for the switch. This is achieved by minimizing the signal-processing electronics typically housed within each module, resulting in less heat generation and lower electricity costs.

Nvidia's role in this development is particularly interesting as the company has also been promoting co-packaged optics (CPO), which integrates the optical engine closer to the switch chip for improved efficiency. While CPO is suited for high-radix switches, the new pluggable format offers flexibility, allowing operators to mix vendors and replace modules without needing to replace the entire switch.

As the demand for 800G-and-faster transceivers is projected to soar, driven by AI cluster expansions, the introduction of this pluggable optics format is poised to make a significant impact on the AI networking landscape.
