CIOE Spotlights Optical Interconnect and Fiber Price Hikes
This issue covers September 6 to September 12, 2026. Shenzhen's CIOE optoelectronics expo was the week's main event: OCS optical circuit switching, silicon photonics chips and new optical fiber were the focus of discussion. Alibaba Cloud says its in-house 400G to 1.6T silicon photonics chips are in volume deployment, and Guangyin Technology unveiled a nanosecond-scale OCS. Fiber supply and demand remain tight, with Corning securing a long-term order for 80 million miles and domestic procurement unit prices up nearly 90%. In research, the Shanghai Institute of Optics and Fine Mechanics reported new progress in multidimensional multiplexed optical computing and microresonator optical frequency combs, while quantum-well metasurfaces advance compact nonlinear devices.
