OPTICAL MODULE AND ASSEMBLY METHOD THEREFOR

An optical module includes a housing, a pull ring assembly, an optical assembly, and a circuit board assembly. An optical interface and an electrical interface are formed at two opposite ends of the housing. The housing includes a bottom wall and two side walls. Two suspension arm accommodating grooves are formed on the two side walls. The pull ring assembly includes two suspension arms and a suspension arm connecting portion. Each suspension arm is disposed in a corresponding one of the suspension arm accommodating grooves. The suspension arm connecting portion is disposed on an external surface of the bottom wall of the housing. When the pull ring assembly moves, the suspension arms are subject to limitation by upper groove walls and lower groove walls of the suspension arm accommodating grooves and move left-right along a direction of a line connecting the optical interface and the electrical interface.
