The ferrule is compressed at the head to hermitically sealed the fiber to the optical package and is compressed at the body to hold the fiber in place. It is apparent to one of ordinary skill in the art that the expression of compressing the ferrule can also be described as mechanically deformed the ferrule, or by other similar or equivalent terms.
