Main applications and markets of fiber amplifiers;

Dense wavelength division multiplexing systems have become the mainstream technology in optical fiber transmission systems. As one of the core components of DWDM systems, fiber amplifiers will develop rapidly in their applications. This is mainly because fiber amplifiers have sufficient gain bandwidth and are compatible with WDM. The combination of technologies can quickly and easily expand the communication capacity of existing fiber optic cable systems and extend the relay distance. In the optical fiber access network, although the distance of the user system is short, the user network has too many branches. Optical fiber amplifiers are needed to increase the power of the optical signal to compensate for the optical loss caused by the optical distributor and increase the number of users, thus reducing the number of users. Network construction costs.
In the optical fiber CATV system, as its scale continues to expand, the transmission distance of the link continues to increase, and the transmission loss of the optical path also continues to increase. The application of optical fiber amplifiers in the optical fiber CATV system can not only increase the optical power, but also compensate for the loss of the link. loss, increases optical user terminals, simplifies the system structure, and reduces system costs.
