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.
