Browave

Passive optics and fiber connectivity for CPO

Published by FyncaResearch checked How we research

Where it fits in an AI server rack

NVIDIA lists Browave in its silicon photonics (CPO) ecosystem (Mar 18, 2025), and Browave announced its selection as an NVIDIA silicon photonics ecosystem partner (Mar 25, 2025). It makes WDM filters, splitters, fiber connectors and planar-waveguide modules, with data-center products for use inside transceivers and for rack-to-rack links.

What the evidence establishes

AI-rack evidence

Partner-disclosed: NVIDIA’s release lists Browave in its silicon photonics ecosystem, and Browave’s website describes its data-center fiber and passive-optics products.

An explicit AI-server or AI-rack product, design-in, supply role, program, reference design or partnership, such as a part named for rack-scale AI systems or a product sold for AI data centers. For a rack builder, it means the company’s own AI servers or racks. This does not establish revenue, market share, volumes or future sourcing.

Company or official disclosure; vendor claims are attributed to their source.
Checked. This is the research review date, not the source publication or quote time.

Keep in perspective

Neither NVIDIA nor Browave describes the specific CPO parts supplied, and Browave’s data-center share of revenue was not verified in our September 2026 review.

Specialist business exposure. This describes the breadth or role of the business; it is not an investment rating. An AI-server product, design-in or partnership does not by itself establish material AI-rack revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Fiber & cabling

High-density optical fiber cables and multi-fiber connectors that carry the light from the rack to the cluster’s switches.

Scope of the company links: Fiber cable, MPO/MMC connectivity and patching from the rack to the network. Corning will raise US optical-connectivity capacity 10x under its May 2026 NVIDIA partnership; Fujikura’s AFL says an NVL72 rack can be fed with up to 1,152 fibers and sells ultra-high-fiber-count cable; Furukawa’s Lightera mass-produces a 13,824-count cable for AI hyperscale data centers; Sumitomo Electric markets a 6,912-fiber cable and high-density connectors; Browave, a Taiwanese passive-optics maker, is in NVIDIA’s CPO ecosystem. SENKO, also named by NVIDIA, is private. The SDM4 multicore-fiber MSA (AFL, Corning, Sumitomo Electric, TeraHop) is a specification, not a product. Other listed cable and connector makers were not verified for AI fiber in our September 2026 review. Amphenol added fiber connectivity with the CommScope connectivity and cable business it bought (closed Jan 9, 2026), and BizLink sells fiber cassettes.
