Abstract
An optical module is disclosed where an optical coupling efficiency between an optical device and an external fiber may be improved. The optical module includes an optical receptacle and a device unit assembled with the optical receptacle only via a stub as forming a gap to isolate these two components. The gap is filled with insulating resin or tightly covered by an insulating ring to reinforce the stub to be hard for an increased moment by the optical assemblies in the device unit.
