In recent years, optical fiber CATV systems, especially 1500nm optical fiber CATV systems, including analog systems and digital systems, have developed rapidly in our country. Erbium-doped fiber amplifiers have also been widely used in optical fiber CATV systems. The power amplifier amplifies the output light of the transmitter at the front end of the CATV system and then distributes it for optical fiber trunk transmission in various directions. The power amplifier and power divider can also be considered as two sections for repeated use.

When branching the fiber optic trunk line away from the front end, an erbium-doped fiber amplifier can be connected in front of the branch as a line amplifier to compensate for the branch loss.
