What we bring today is a 1550nm fiber-coupled acousto-optic modulator with a driver. The 1550nm acousto-optic modulator is an external modulation technology, and the acousto-optic device that controls the intensity of the laser beam is usually called an acousto-optic modulator. The 1550nm AOM has the advantages of high modulation extinction ratio and high power withstand, and is widely used in the field of optical fiber sensing. This acousto-optic modulator is coupled to a single-mode fiber, and custom polarization-maintaining fibers are also available. In addition, the working wavelength and RF frequency of AOM can also be customized. The test report of 1550nm 200MHz SM fiber coupled AOM.
