      It is the opposite function of the amplifier,from his name it attenuate the signal power but it may be just a length of fiber.
      Yes ,It increase BER for two reasons,1-it produces noise.,2-It decreases power and hence decrease OSNR which increase BER.

      Hi Abdullah,

      You can use your attenuator either at the transmitter or at the receiver. It will depend on your scheme and the main design purpose.
