Optical Communication Coating Solution

Optical communication refers to communication using light waves as the carrier.

There are two main ways to increase optical bandwidth:

One is to increase the transmission rate of a single channel in the optical fiber;

The other is to increase the number of wavelengths transmitted through a single fiber, which is known as Wavelength Division Multiplexing (WDM) technology.

In fact, optical communication equipment is typically only suitable for use over the last few kilometers of distance.
