In this paper, the design of a 1 × 8MEMS optical wavelength channel selector drive circuit, the use of the circuit in the serial port signal conversion chip optical wavelength channel selector and the computer connected to the computer interface to achieve 1 × 8 optical wavelength channel selector working state The choice and control. Using optical platform, precision optical fiber adjustment frame, high stability light source and optical power meter and other equipment on the 1 × 8 wavelength channel selector unit for positioning and integration. The response time and insertion loss of 1 × 8 optical wavelength channel selector were designed and established. The response time and insertion loss of 1 × 8 optical wavelength channel selector were measured. The experimental results show that the 1 × 8 optical wavelength channel Selector response time is about 15ms, the maximum insertion loss of about 2.5dB.
