Our company established in 1999 specialized in ASIC(Application Specific Integrated Circuit) and we became a global leader of security products by the commercial adoption of CAM and CableCards embedded with CAS chip, protecting contents in line with a convergence between broadcasting and telecommunications since 1999. However we have recognized that the optical market is one of blue ocean ones for the broadband transmission of various information including audio, video and broadcasting, which has been caused by organic combination of information between individuals and their participations in Web 3.0 age and thus, we have set up the newest production line with automated systems in Gwang-Ju optical industry complex for the mass production of optical wafers and chips used for optical splitters which is a core part of FTTx(Fiber to The X).
