Zaram Technology

Zaram Technology makes semiconductor chips and related hardware that carry high-speed internet signals over fiber-optic networks into homes and buildings.

Its core products include a communications chip, known as an XGS-PON system-on-chip, and a compact optical module that converts light signals from a fiber cable into the electrical signals a subscriber's equipment can use. Telecom operators and network equipment makers are the broad end-users of these components. The company is listed on KOSDAQ, South Korea's tech-focused small-cap exchange.
