Abstract
The present invention provides an optical transceiver with a structure that is able to cope with both the heat-dissipation and the optical coupling of the sub-assembly with a butterfly package. The optical transceiver includes a frame, a receptacle member, a transmitter optical sub-assembly, a receiver optical sub-assembly, a substrate and a cover. At least one of sub-assemblies provides, what is called, a butterfly package assembled with the receptacle member. The assembly of the receptacle member with the sub-assembly is fixed to the frame with an elastomer put between the receptacle member and the frame. The sub-assembly is assembled with the receptacle member as satisfying the optical alignment, while, the assembly of the receptacle member and the sub-assembly is fixed to the frame in a unit. Accordingly, the optical alignment and the fixing to the frame are consistently satisfied.
