1550nm dual output fiber coupled acousto-optic device (all fiber acousto-optic modulator)
The Xiaoxiao photon all fiber acousto-optic modulator allows users to change the output light amplitude, duration, and period/frequency. The insertion loss can be as low as 2 dB, the extinction ratio can be as high as 50 dB, the rise time can be as low as 5 nanoseconds, and the periodicity can be as high as several hundred MHz. Applications include switches, pulse pickups, fast attenuators, etc. The wavelength range is from near ultraviolet to near infrared. A special application of modulators is programmable attenuators. Attenuator is a key component in the design of fiber optic transmission systems. Attenuators are used to match the optical power level with the dynamic range of the receiver, adjust the input and output levels in EDFA, balance the power between different DWDM channels, and test the overall performance of the system under different optical power conditions.
