Abstract:
A fiber optic transmitter module comprising:a printed wiring board defining a notch in at least one edge thereof and arm portions that define opposite edges of the notch; an integrated circuit mounted upon a medial portion of said printed wiring board such that said printed wiring board mechanically supports said integrated circuit, said integrated circuit comprising a driver circuit for providing a drive current; and a transmitter optical subassembly comprising a receptacle and a light source, said receptacle defining an internal cavity for receiving the light source and a pair of slots proximate the internal cavity and spaced apart from one another on opposite sides of the internal cavity for receiving respective arm portions of said printed wiring board without also receiving the light source, said light source being responsive to said driver circuit for transmitting signals in response to the drive current, said transmitter optical subassembly mounted to said printed wiring board so as to be at least partially disposed in the notch defined by said printed wiring board to thereby reduce path length between said light source and said integrated circuit and to correspondingly reduce circuit parasitics.
