Troubleshooting of 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. They are indispensable key components in the new generation of optical fiber communication systems.

Fiber amplifiers mainly include erbium-doped fiber amplifier (EDFA), semiconductor optical amplifier (SOA) and fiber Raman amplifier (FRA). Optical fiber amplifiers are very critical in optical fiber communication systems, but they are also prone to failures. The following briefly introduces the failures and processing methods of optical fiber amplifiers.

 

The display on the panel of the optical fiber amplifier is synchronized with the actual output. If the display on the panel is normal, it means that the output of the optical amplifier is normal. If the optical power of the optical amplifier is dropped or not enough in this case, the following situations may occur:

 

(1) The optical power meter is inaccurate. The domestic optical power meter can only test equipment with small optical power output, and cannot test EDFA with high power output. The optical power meter for testing optical amplifiers must be imported with original packaging, and inaccurate instruments cannot be used Use it as a standard.

 

(2) The flange of the output port is damaged (less likely).

 

(3) Improper use by the user, plugging and unplugging the pigtail when the machine is working, burns the pigtail head of the optical amplifier output, resulting in a decrease in the output power of the optical amplifier. If this happens, just re-splice the output connector of the optical amplifier.

 

(4) The quality of the pigtail used by the user is poor, the fiber core is too long, and the output connector of the optical amplifier is scratched after the pigtail is inserted. This phenomenon is that the first test is good, and the optical power drops after the second insertion and re-test . If this happens, just re-splice the output connector of the optical amplifier.

 

(5) The wavelength of the light source is wrong. If the wavelength of the 1550nm optical transmitter deviates, the output optical power of the optical amplifier will be insufficient, and the panel display will also be too small.

 

(6) The optical power input to the optical amplifier is small. If it is lower than the standard value, the optical power may become smaller, and the panel display will also become smaller.
