mechanically induced modulation

mechanically induced modulation: Optical signal modulation induced by mechanical means. Note: An example of deleterious mechanically induced modulation is speckle noise created in a multimode fiber by an imperfect splice or imperfectly mated connectors. Mechanical disturbance of the fiber ahead of the joint will introduce changes in the modal structure, resulting in variations of joint loss.
