Abstract
A detachable fiber optic connector has an improved nose block (800) which enhances cooling of power dissipating components, simplifies assembly, improves yield and reduces cost. The improved nose block (800) includes an upper tray (802) and lower tray (804) which slidingly receive an improved aluminum nitride optical subassembly (700). The subassembly (700) and nose block (800) are held together, properly aligned, and then fixated. The nose block (800) also has symmetrical protrusions (850) which allow the nose block (800) to be placed easily and precisely into mating protrusions (230, 240) in a seal ring (200). The nose block (800) provides a direct thermal pathway between power dissipating components, such as an opto-electronic component (750) and optical driver IC (730), and an aluminum package base (400). Various alternative nose blocks (810, 820, 830) are illustrated, and an alternative base (410) is also shown. The package is completely sealed to ensure field reliability, and manufactured using low cost processes.
