Combined optical and electrical interface
A connection port provides electrical and/or optical interface capability. The combined electrical and optical interface port may include an optical communication light engine within the connection port itself. The connection port includes a connector housing, an electrical interface assembly, and an optical interface assembly incorporated together. One implementation of the optical communication light engine includes a laser diode to generate optical signals, a photo diode to receive optical signals, and an optical integrated circuit (IC) to control optical interface.
1. An input/output (I/O) apparatus comprising:
an input/output connector wherein the input/output connector comprises both electrical and optical input/output interfaces and the optical input/output interface comprises at least one optical lens,
at least one optical fiber wherein a first end of the at least one optical fiber terminates in the input/output connector and is optically coupled to the at least one optical lens, and
a transceiver module to convert optical signals into electrical signals wherein the transceiver module comprises at least one lens, wherein a second end of the at least one optical fiber terminates in the transceiver module, and wherein the input/output connector and the transceiver module are not coterminous.
