Photonics startup Lightmatter unveiled the Passage L20 near-package optical engine and vClick surface fiber array ahead of OFC on Wednesday. The 6.4 Tbps L20 uses bidirectional 200 Gbps fibers to halve fiber counts versus pluggables and attaches near the ASIC rather than co-packaging, while vClick enables wafer-level surface testing for advanced packaging. Lightmatter plans sampling in late 2026.
Key Points
- 1Announces 6.4 Tbps Passage L20 optimized for near-package optics and bidirectional 200 Gbps fibers
- 2Reduces fiber count by roughly half compared with single-direction pluggables, lowering cost and cabling complexity
- 3Enables scale-up switches to replace 512 pluggables per 102.4 Tbps switch, saving power and space
Scoring Rationale
New NPO product offers tangible cabling and power savings, but scope remains limited until broader CPO adoption.
