Who We Are
Who We Are
On October 1, 1974, Taihan Fiberoptics established a communication infrastructure for Korea to connect to a bigger world.
Since that moment, Korea connected with the world and realized the world's first 5G and Taihan Fiberoptics has always been a part of this network innovation.
with communication innovation
Today, we connect to a bigger world in many different forms. Taihan Fiberoptics will always be with you
from the beginning where connection allows us to meet new possibilities and make possibilities become reality.
