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.
