Patents by Inventor Yongbu HAILAI

Yongbu HAILAI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Methods of reducing or eliminating internal optical light reflections, increasing yield, reducing high-temperature transmission failures and/or improving OSA transmission performance and an improved optical transceiver implementing the same
    Patent number: 10326527
    Abstract: An optical transceiver and a method of making the same. The optical transceiver includes a base/housing having a roughened or darkened optics mounting surface, a transmitter optical subassembly (TOSA), a receiver optical subassembly (ROSA), a beam splitter mount secured to or mounted on the roughened or darkened optics mounting surface, a beam splitter secured to or mounted on the beam splitter mount, and an optical fiber adapter. The TOSA includes a laser diode configured to convert a received electrical signal to an outgoing optical signal. The ROSA includes a photodiode configured to convert a received optical signal to an outgoing electrical signal. The beam splitter is transparent to one of the outgoing and received optical signals and is configured to reflect the other. The optical fiber adapter is configured to hold an optical fiber that receives the outgoing optical signal and provides the received optical signal.
