Low-power N-type Acousto Optic Driver for 1550nm Fiber AOM Series
The Type N /N2 acousto-optic driver is an RF signal generator designed to drive acousto-optic modulators or frequency shifters with a power of less than 3W. It produces a radio frequency electrical signal acting on an acousto-optic modulator, which is converted into an ultrasonic wave of the same frequency by a piezoelectric transducer. After a series of acousto-optic effects, the nature of light will change. The frequency and strength of the RF signal directly controls the degree to which the beam is modulated, deflected, or tuned. Drive efficient heat dissipation, reliable operation, and use of matching drives to further improve temperature stability.
| Supporting Drive | Model SGXXXX-33-N-ab offers two functionalities: “X” designates its ability to shift frequencies, while “T” indicates its modulation capability. “XXX” represents the operating frequency, and “33” specifies the RF output power. The letter “N” denotes the package type. Power supply options are 24V (marked as “1”) and 12V (“2”). Finally, “D” signifies digital TTL modulation capability, while “A” indicates analog modulation. | ||||||
