Optical fiber amplifiers multiply the photon stream by means of electronic excitation. The term also refers to fiber optic sensors. The application These devices are used to amplify signals in long-distance fiber-optic communication systems. Automatic fiber optic sensing includes detecting the passage of objects. technology In optical fiber communication, the signal is enhanced at regular intervals. The most common method is to use laser pumping to stimulate erbium-doped fiber amplifiers (EDFA). There are other doping systems, and a technique that exploits the Raman effect. Fiber optic sensing is realized by interruption or reflection of laser beam. Generally, each unit has two optical and electrical connections for power and signal detection. Sensitivity is adjustable and the device may be able to self-adjust based on past experience. How to choose Select communication equipment according to signal frequency range and transmission distance. For sensing devices, the choice will depend on the required functional complexity and response time.
