Since joining Samsung Electronics Co. in 1987, I have established ETRADINGKOREA. Co.,Ltd based on 10 years of experience in sales and technology related work in electronics and telecommunications, and 5 years of marketing, trade, technical support, and product development experience in NI company to develop and supply optical modules and industrial network switches.

Since our foundation in 2006, we have supplied "PREMIUM" brand optical modules to customers such as Samsung Electronics, Korea Telecom, SK Broad Band, Army, Navy, Air Force and Defense Acquisition Program Administration, Seoul National University, and Korea Railroad, and have been recognized by our customers for their good quality, prompt delivery, careful consulting, and perfect technical support.

In addition, we have been developing high-quality industrial bypass switches since 2017, and have been operating stably by delivery to the Korea Railroad and the Navy.

Considering that the industrial switch is used for more than five years once purchased, we use high-quality parts to supply a product with upgraded performance.

Based on its excellent quality, ETK-4000B 40 units were supplied to the Korea Railroad in 2018 and ETK-5000B 150 units for naval port docks in 2019. In May 2019, the company passed the TTA test certification for the delivery of industrial switches for ITS for road construction and opened the way for delivery to public institutions.

We promise to continue to develop the various performance industrial switches and optical modules needed by our customers and to work with 5G leading IT companies to provide them with reasonable prices and services that they can meet.

Thank you for your trust in our partner and customer executives and employees, and we will continue to do our best to maintain and develop that trust.
