The product portfolio spans seven FOG optical module series (32, 37, 42, 50, 70, 98, 120) targeting bias stabilities from 0.7°/h down to 0.001°/h, polarization-maintaining, rare-earth-doped and photonic crystal specialty fibers, distributed temperature and vibration sensing systems, Raman-OTDR-based perimeter and pipeline monitoring, FOCT smart grid sensors, fiber coil winding equipment, and 1550nm/1535nm fiber laser products. Primary customer segments are aerospace and defense, smart grid and power utilities, and marine/ocean monitoring, with secondary demand from fiber laser manufacturers, industrial end-users, and academic/research institutions (including National University of Defense Technology, Huazhong University of Science and Technology, and Wuhan University of Technology).

YOEC operates a sales-led B2B go-to-market with an event overlay (CIOE, Wuhan Optoelectronics Expo, Munich Shanghai Photonics Expo), distributing solely through a direct technical sales force segmented by product domain with no third-party distributor network disclosed. Geographic footprint is China-domiciled with select international inquiries managed through a dedicated overseas sales email; the company is headquartered at No. 80, Gaoxin 5th Road, East Lake New Technology Development Zone, Wuhan, with an Ezhou manufacturing subsidiary that commenced operations in June 2026, and a metrology services subsidiary (Wuhan Optical Valley Metrology Co., Ltd.). Headcount is reported in the 501-1,000 band. The firm has no parent or controlling shareholder disclosed and operates as an independent joint-stock limited company listed on the Shanghai STAR Market.
