With an aggregate capacity of 6.4 Tb/s, the Vesta 200 6.4T CPX performs electrical-to-optical and optical-to-electrical conversion using 32 transmit (Tx) and 32 receive (Rx) channels. Its design aims to facilitate integration with next-generation ASICs within an open ecosystem, combining high interconnect density with reduced power consumption.
Although the device was primarily designed for 32 × 200 Gb/s applications over a single wavelength, its architecture is not tied to a specific data rate or protocol. This flexibility allows it to be used in various network configurations.
Supported configurations include 32 × 200GBASE-DR1, 16 × 400GBASE-DR2, 8 × 800GBASE-DR4, and 4 × 1.6TBASE-DR8. Versions of these specifications for links up to 2 km are also available.
Prepared for CPO and NPO architectures
One of the highlights of the Vesta 200 6.4T CPX is its focus on Near-Packaged Optics (NPO) and Co-Packaged Optics (CPO) applications, technologies that bring optical interfaces closer to ASICs with the aim of increasing bandwidth density and optimizing the energy consumption of interconnections.
The optical engine incorporates a compact CPX connector, allowing the same printed circuit board (PCB) to be used for different CPO and Co-Packaged Copper (CPC) configurations. This feature provides manufacturers with flexibility when developing platforms capable of adapting to various interconnect architectures.
The Vesta 200 6.4T CPX has also been designed to work with standardized O-band optics and plug-in external laser source (ELS) modules. This aims to promote interoperability between systems and simplify laser maintenance and replacement.
Standardized interfaces and up to 32 channels of 200 Gb/s
Among its main technical features, the Vesta 200 6.4T CPX offers 32 optical channels of 200 Gb/s, a standards-based electrical host interface and dual +3.3 V and +5.0 V power.
Compatibility with interoperable O-band optics and pluggable external laser sources completes an architecture aimed at new high-capacity optical communication systems, where the proximity between electronic processing and optical interfaces is becoming increasingly important.
With this combination of capacity, density, and integration flexibility, the Vesta 200 6.4T CPX positions itself as a solution for the development of next-generation optical connectivity platforms for data centers, artificial intelligence infrastructures, and high-performance computing systems.
