variable optical attenuator using the optical fiber coupler

摘要

Fiber Optic Coupler relates to a variable optical attenuator using , and the home is wave excitation waveguides , waveguide on one end is connected to the other end of the groove portion and the end of the waveguide optical variable for varying the strength of the input optical signal , being composed of a fiber coupler that separates a monitor output for monitoring the output state and the output state for outputting the optical signal , the size of the entire device smaller and reduces the cost of the entire device as a result and can also reduce the number of optical Kerr contactor .
