ABSTRACT:
A method for upgrading an optoelectrical system includes securing a transmitter to a line card, wherein the line card comprises an optoelectrical connector. It also includes coupling the transmitter to the connector, wherein the connector comprises an embedded fiber configured to be coupled to the transmitter. In addition, the method includes inserting a pluggable form factor module comprising a receiver, an input port, and an output port into a cage secured to the line card. Further, the method includes coupling the pluggable form factor module to the connector such that an optical signal transmitted by the transmitter propagates in an optical line of sight between the embedded fiber of the connector and the output port. The connector comprises electrical contacts that are configured to be coupled to the module such that the receiver can convert optical signals received at the input port into electrical signals and transmit the electrical signals to the line card via the connector.
