Working principle
The working principle of the multi-channel single-mode 0~40dB optical attenuator is mainly based on the attenuation mechanism of the optical signal in the transmission process, including light absorption, light scattering, light reflection and attenuation technology based on optical fiber dislocation or displacement. By controlling these mechanisms, the optical signal intensity can be precisely adjusted.
Application field
Telecommunications industry: Used in optical fiber communication networks to regulate the power of optical fiber signals, prevent excessive signal strength from causing damage to the optical fiber system, and protect the normal operation of the system.
Network industry: In the network signal transmission, by adjusting the signal power, improve the stability of network equipment and transmission quality.
Television broadcasting industry: In the transmission of broadcast signals, the signal power is adjusted to protect the broadcast system from interference caused by excessive signal strength.
Safety industry: In the safety equipment, by adjusting the signal power, to prevent the system from generating noise due to too strong signals, improve the safety and stability of the system.
