4 Channel Optically Controlled Optical Attenuator 12 Wavelength Calibration
The 4-channel optical-controlled optical attenuator is a device widely used in the field of optical communication. It has the characteristics of multi-channel design, precise control and high reliability, and can meet the test requirements of complex optical fiber communication systems.
The 4-channel optically controlled optical attenuator integrates four independent optical attenuator channels, each of which can be adjusted independently for optical signal attenuation. This design not only saves equipment footprint, but also significantly improves test data throughput and test rate. By precisely controlling the attenuation of optical signal in each channel, the optical signal transmission under different transmission conditions can be simulated, which provides strong support for system optimization.
