PON (Passive Optical Network) technology is becoming common as new technologies are emerging due to the development of network technology, and as the movement to provide better service to broadband users continues. It is a very efficient system because it can provide multi-service with one device and it can flexibly adapt to network environment.

FTTx stands for “Fiber to the x” and refers to the network structure of optical fiber that replaces the telephone network, which is typically a copper wire. Among these, fiber-to-the-home (FTTH) refers to a service that provides broadband Internet by installing fiber-optic cable to the house.
