Explore communication technologies!

Communication is essential in our daily life. We take the communication systems for granted, while much has been done to ensure that communication would not be disrupted easily. Let’s learn about communication systems through the displays.

  • Optical communication

    Have you heard of “optical communication?” Why does it have to be optical? Because light has high frequency(oscillation per second) and can transmit a lot of information.

  • Fiber optics

    Fiber optics uses a property of light called “total internal reflection” which enables the transmission of massive data at a high speed. It has a three-layered structure comprised of core, cladding, and coating.

  • Total internal reflection

    When light goes from a medium such as water, glass or plastic to the atmosphere, all the light will be reflected if it strikes the medium boundary at a large angle of incidence.
