​Global Technology and ADST to Develop Domestic UV Light Sources for CPO Alignment Equipment

What happened

Global Technology said on Oct. 12 that it has begun co-developing ultraviolet (UV) curing light source units for ADST's active alignment equipment; ADST is a subsidiary of Sungho Electronics. The equipment is used to manufacture CPO systems and high-speed optical transceivers. The project will cover UV-curing LED driver ICs, UV LED light source modules, and control units. Active alignment equipment performs optical alignment in CPO mass-production processes, positioning fibers, lenses, and optical devices with sub-micrometer accuracy before securing them with UV-curable adhesive; UV output and exposure time must be precisely controlled to minimize shrinkage and positional displacement during curing. Global Technology noted that domestic equipment manufacturers have largely relied on imports for these UV curing light sources. This is the companies' second collaboration, following their micro-LED partnership for next-generation displays. The two companies plan to build a domestic mass-production ecosystem and localize key equipment components; after development is completed, they are considering deploying the light source units in ADST's equipment. Sungho Electronics, ADST's parent company, is a strategic investor in Global Technology. Industry participants expect CPO commercialization to accelerate in 2027 or 2028 when 1.6T-class equipment adoption begins.
