NEC Laboratories America is proud to participate in OECC 2026, the 31st Opto-Electronics and Communications Conference, taking place in Busan, South Korea.

As a global leader in applied research spanning optical fiber sensing, network systems, and AI-driven communications technologies, our team will showcase our latest disruptive research.

OECC 2026

From advanced transmission systems and optical fiber sensing to AI and machine learning for network design and management, our researchers are actively advancing the field across multiple OECC technical tracks. We look forward to connecting with the international photonics and communications community and sharing the work we’re doing to shape the next generation of optical networks.

OECC Presentations

Multi-Fiber/Multi-DAS Array System with Clock-Free Synchronization

Wataru Kohno NEC Labs America

We demonstrate distributed fiber-optic acoustic sensing that employs a mechanical synchronizer to achieve sample-level synchronization of signals across independent sensors. This enables phase-noise suppression and bandwidth extension in standard multi-fiber optical cables without hardware modification.

Rapid State-of-Polarization Change-Point Detection via Minimum Lossy Coding Length

Ming-Fang Huang NEC Labs America

We propose a rapid state-of-polarization disturbance change-point detection and localization method using lossy coding length of kernel features. Field experiments validate accurate detection of subtle changes and precise localization, enabling reliable fiber identification and monitoring.

Field Trial of Urban Monitoring over Telecom Networks with Rayleigh-based DTSS

Ming-Fang Huang NEC Labs America

We present a field trial on urban monitoring over telecom networks using Rayleigh-based distributed temperature/ strain sensor (DTSS), showing the capability of detecting subtle infrastructure signatures, including manhole locations, road traffic, sprinklers, and underground leakage events.

A Low-cost Wavelength Selectable Distributed Vibration Sensor with a Unified Sensitivity for the Whole Route Security Monitoring in PONs

Yaowen Li NEC Labs America

We demonstrate a low-cost wavelength-selectable distributed vibration sensor to monitor the whole routes in a 1×32 PON architecture with a unified sensitivity. The results obtained from the lab and a field testbed are presented.

Bridging the Domain Gap in DAS: Adapting Vision Foundation Models for Infrastructure Security

Ming-Fang Huang NEC Labs America

Distributed Acoustic Sensing may suffer severe cross-day domain shift. We bridge this gap by encoding 1D phase signals into physics-informed 3-channel gradient tensors and adapting Vision Foundation Models (ViT-B/16), achieving superior threat detection over baselines.

Mobile Orbital Domain-based Hierarchical Routing with Joint Path and Gateway Selection

Philip Ji NEC Labs America

We propose to jointly optimize path and gateway selection to achieve load balancing for mobile orbital domain -based hierarchical routing in satellite networks. The load at bottleneck gateway satellites can be reduced by 22% on average.
