Abstract: A fiber waveguide optical subassembly uses the multi-mode fiber to increase the alignment tolerance between the active optical element and the waveguide. The filter is thinner to lower the dispersion due to the optical coupling gap. The subassembly further combines the optical bench to achieve passive positioning. Therefore it reduces the cost and enhances the transmission rate.

Abstract: The eject-lever apparatus of the present invention is arranged in an optical transceiver having a substrate, where the optical transceiver is being received in a housing having a slot arranged therein with the substrate being plugged into the slot, the apparatus comprising: at least a lever having a cam arranged therein, being disposed at the receiving end of the optic fiber of the optical transceiver; and at least a linkage rod, being deposed on a side of the optical transceiver, wherein the lever is actuated to rotate about an axis from a first location thereof to a second position thereof by exerting a force thereon while driving the cam to rotate accordingly for transmitting the force to an end of the linkage rod enabling the linkage rod to exert a force on the housing so as to generate a reacting force acting on the lever and thus cause the optical transceiver to move out to compress an elastic body and be ejected from the slot gradually; finally, the substrate is totally released from the slot for freei
