Patent ID: 8238699

Claim:
An optical transceiver integrated circuit (IC) comprising: a single IC substrate having multiple cells integrated on the single IC substrate and the multiple cells being vertically arranged with respect to each other and to the single IC substrate, each cell being optically isolated from each other cell with at least one cell being configured to operate at one bitrate and at least another cell being configured to operate an another, different bitrate, each cell including: an optoelectronic transducer on an optoelectronic transducer substrate and being optically coupled to an optoelectronic transducer optical port that is configured to be operably coupled to a first optical fiber of a network, the optoelectronic transducer substrate being mounted on the IC substrate; and an electro-optic transducer on an electro-optic transducer substrate and being optically coupled to an electro-optic transducer optical port that is configured to be operably coupled to a second optical fiber of the network, the electro-optic transducer substrate being mounted on the IC substrate; a post-amplifier integrated on the IC substrate and configured for communication with the optoelectronic transducer; an electro-optic transducer driver integrated on the IC substrate and configured for communication with the electro-optic transducer; and a control module integrated on the IC substrate and configured to control the operation of at least one of the electro-optic transducer driver and the post-amplifier, wherein the optoelectronic transducer substrate, the electro-optic transducer substrate, the post-amplifier, the electro-optic transducer driver, and the control module are integrated together and the optoelectronic transducer substrate is a separate substrate from the electro-optic transducer substrate, and the optical transceiver IC is devoid of a printed circuit board (PCB).
