Salience Labs has announced $125 million in Series B financing to expand its silicon-photonics-based optical circuit switching technology for AI data center networks.
Salience has demonstrated a 64-port optical circuit switch, positioning the technology for evaluation in AI fabrics where bandwidth demands and network reconfiguration are increasing. The new funding is intended to support manufacturing scale-up and commercial deployment.
Optical circuit switching is complementary to, rather than a direct substitute for, packet switching in many network designs. Adoption will depend on application requirements, control software and integration with existing fabrics.
