OFS Labs is the research division of OFS, a leader in fiber optic solutions. NEC Labs America collaborates with OFS Labs in optical fiber design, amplification technologies, and distributed sensing systems. Joint research accelerates advancements in subsea cables, photonic systems, and high-performance optical networking. These collaborations ensure that NEC’s innovations in sensing and communication are validated against industry standards and integrated into global infrastructure.
We report significant noise reduction in distributed acoustic sensing (DAS) link using enhanced-scatter fibre (ESF). The longest reach of 195km DAS link without inline amplifications is also demonstrated. We further present demonstration of simultaneous fibre-optic sensing and 400Gb/s data transmissions over 195km fibre using ESF.
