Lightmatter's Detachable Optics Aim to Unlock CPO Scaling
Event summary
- Lightmatter unveiled vClick Optics, a detachable fiber array unit (FAU) technology designed to address scaling challenges in Co-Packaged Optics (CPO).
- vClick Optics integrates with SENKO’s SEAT™ and MPC Connector solutions and is compatible with ASE’s advanced packaging flows.
- The technology demonstrates a low insertion loss of less than 1.5 dB and supports high-bandwidth Dense Wavelength Division Multiplexing (DWDM).
- Lightmatter also introduced eClick Optics, an edge-coupling solution for larger die complexes, complementing the vClick offering.
- Lightmatter will showcase these innovations at the Optical Fiber Communication conference in Los Angeles, March 15-19, 2026.
The big picture
Lightmatter’s vClick Optics represents a critical step toward overcoming the scaling bottlenecks currently hindering the widespread adoption of Co-Packaged Optics (CPO) for next-generation AI and high-performance computing. The ability to detach fiber arrays simplifies manufacturing, reduces yield loss, and enables easier field servicing, all of which are essential for hyperscale deployments. This innovation positions Lightmatter to capitalize on the growing demand for higher bandwidth and energy-efficient interconnect solutions in the rapidly expanding AI infrastructure market.
What we're watching
- Manufacturing Adoption
- The speed at which ASE and other foundries integrate vClick Optics into their high-volume manufacturing processes will determine the technology's near-term impact on CPO scaling.
- Competitive Response
- How other photonic interconnect vendors will react to Lightmatter’s detachable FAU approach, and whether they will develop competing solutions, will shape the long-term landscape of CPO technology.
- Serviceability Impact
- The demonstrated field serviceability of vClick Optics will be a key factor in its adoption by hyperscale data centers, as it directly addresses a major operational challenge with CPO deployments.
