VOA Fiber Optical Patch Cord (Variable Optical Attenuator Patch Cord) combines the core technology of Variable Optical Attenuator (VOA) to achieve real-time adjustment of optical signal intensity by precisely controlling the attenuation amount of optical signals. The application of VOA attenuation patch cords in optical networks provides important guarantees for the stable transmission of optical signals. It has a wide attenuation adjustment range, usually adjustable between 2 dB and 10 dB, providing greater flexibility and adaptability for optical networks.
