Optoelectronics Business

SOC manufactures and supplies LiNbO3 modulator which converts electrical signal to optical signal (modulation) for optical communication systems.
SOC has been developed and manufactured the state-of-the-art LN modulator technology for more than 25 years and keeps supporting the customers all over the world.
In 2014, we introduced a new logo of “Sumicem” for the product of opto-electronics business division. The logo, “Sumicem”, is a proof of the achievement we had been made from 1994.
SOC’s modulators are used not only for telecommunication but also for non-telecommunication application like CATV transmission systems, Test & Measurement systems and RoF systems.


SOC has been supplying LN modulators for optical communication systems that require high reliability since 1994. Our modulators are qualified for the Telcordia GR-468-CORE.
