Optical fiber amplifier
Optical fiber amplifiers can not only directly amplify optical signals, but also have real-time, high-gain, broadband, online, low-noise, and low-loss all-optical amplification functions.
It is an indispensable key component in a new generation of optical fiber communication systems;
Because this technology not only solves the limitation of attenuation on the transmission rate and distance of the optical network, but more importantly, it creates wavelength division multiplexing in the 1550nm frequency band, which will enable ultra-high-speed, ultra-large capacity, and ultra-long-distance wavelength division multiplexing.
(WDM), Dense Wavelength Division Multiplexing (DWDM), all-optical transmission, and optical soliton transmission have become a reality, which is an epoch-making milestone in the history of optical fiber communication.
Among the currently practical fiber amplifiers, there are mainly erbium-doped fiber amplifiers (EDFA), semiconductor optical amplifiers (SOA), and fiber Raman amplifiers (FRA).
Among them, erbium-doped fiber amplifiers have been widely used in long-distance, large-capacity, high-speed optical fiber communication systems, access networks, optical fiber CATV networks, military systems (radar multi-channel data multiplexing, data transmission, guidance, etc.), and other fields, as power amplifiers, relay amplifiers, and preamplifiers.
Fiber amplifiers are generally composed of the gain medium, pump light, and input-output coupling structure.
At present, fiber amplifiers mainly include erbium-doped fiber amplifiers, semiconductor optical amplifiers, and fiber Raman amplifiers.
According to its application in optical fiber networks, optical fiber amplifiers mainly have three different uses:
Used as a power amplifier on the transmitter side to increase the power of the transmitter;
Make an optical pre-amplifier before the receiver to greatly improve the sensitivity of the optical receiver;
Used as a relay amplifier in the optical fiber transmission line to compensate for the optical fiber transmission loss and extend the transmission distance.
