Patent ID: 8556523

Claim:
An opto-electronic transceiver device comprising: a housing for mounting in a host device; a printed circuit board (PCB) mounted in the housing including Rx+ and Rx− inputs, and Tx+ and Tx− outputs; an optical input mounted on the housing for receiving an optical signal from an optical network; a receiver optical subassembly (ROSA) for converting the optical signal into a differential electrical signal comprising inverted Rx+ and Rx− components; a ROSA interconnect for transmitting the Rx+ and Rx− components from the ROSA to the Rx+ and Rx− inputs on the PCB; a first inverter for inverting the inverted Rx+ and Rx− components from the ROSA providing original Rx+ and Rx− components; an electrical connector including: Rx+ and Rx− output leads electrically coupled to the Rx+ and Rx− inputs on the PCB via electrical traces on the PCB for transmitting the original Rx+ and Rx− components to the host device, and Tx+ and Tx− input leads for transmitting a differential electrical signal from the host device including original Tx+ and Tx− components electrically coupled to the Tx+ and Tx− outputs on the PCB via electrical traces on the PCB; a TOSA interconnect electrically coupled to the Tx+ and Tx− outputs on the PCB for transmitting the Tx+ and Tx− components from the Tx+ and Tx− outputs; a second inverter for inverting the original Tx+ and Tx− components from the Tx+ and Tx− input leads on the electrical connector providing inverted Tx+ and Tx− components; and a transmitter optical subassembly (TOSA) including Tx+ and Tx− inputs electrically coupled to the Tx+ and Tx− outputs on the PCB via the TOSA interconnect for converting the inverted Tx+ and Tx− components into an optical signal, and transmitting the optical signal to the optical network.
