Abstract: A transceiver can include a transmitter and a receiver. The transmitter can include: a primary laser emitter; a primary monitor photodiode optically coupled with the laser emitter; a spare laser emitter; and a transmitter integrated circuit having a primary channel operably coupled with the primary laser emitter; a spare channel operably coupled with the spare laser emitter; a switch on the primary channel; and a secondary channel operably coupled with the switch and the spare channel. The receiver can include: a primary detector photodiode; a spare detector photodiode; and a receiver integrated circuit a primary receiver channel operably coupled with the at least one primary detector photodiode; a spare receiver channel operably coupled with the spare detector photodiode; a receiver switch on the spare receiver channel; and a secondary receiver channel operably coupled with the receiver switch and the primary receiver channel.

Abstract: A system may include a substrate and a lens component. The substrate may include pads and solder protuberances. Each solder protuberance may be located on a pad. The lens component may define grooves sized to receive at least a portion of the solder protuberances. The lens component may be positioned relative to the substrate such that at least a portion of each solder protuberance is positioned within the grooves.

Abstract: An optical fiber securing device may include a passage, an optical fiber seat, and a boundary portion. The passage may have an entrance and an exit, the passage configured to receive therein an optical fiber inserted through the entrance, as well as an epoxy. An epoxy path may be provided as a pathway between an epoxy well and the passage. The optical fiber seat may be configured to receive at least a portion of the optical fiber, the optical fiber seat configured to position an end of the optical fiber in optical alignment with a lens. The boundary portion may define an upper boundary of the passage at the exit of the passage, and is configured to restrain epoxy received within the passage such that the epoxy does not become interposed between the end of the optical fiber and the lens.

Abstract: An optically enabled multi-chip module has an optical engine transceiver and a host system chip. The optical engine transceiver has an optical engine front-end and an optical engine macro. The optical engine front-end has multiple laser diodes, laser driver circuitry electrically interfaced with each of the laser diodes, multiple photodiodes, amplifier circuitry electrically interfaced with each of the photodiodes, and at least one optical element optically positioned between the laser diodes and at least one optical fiber and between the photodiodes and the at least one optical fiber. The at least one optical element optically interfaces the laser diodes and photodiodes with the optical fiber. The optical engine macro is both electrically interfaced with and physically segregated from the optical engine front-end. The optical engine macro provides a subset of optical transceiver functionality to the optical engine front-end. The host system chip is electrically interfaced with the optical engine transceiver.
