    Abstract: First data is received on a plurality of data lanes of a physical link and a stream signal corresponding to the first data is received on a stream lane identifying a type of the first data. A first instance of an error detection code of a particular type is identified in the first data. Second data is received on at least a portion of the plurality of data lanes and a stream signal corresponding to the second data is received on the stream lane identifying a type of the second data. A second instance of the error detection code of the particular type is identified in the second data. The stream lane is another one of the lanes of the physical link and, in some instance, the type of the second data is different from the type of the first data.

    Abstract: A redriver device is provided to receive signals from a first device and forward the signals to a second device on a differential link. Detection circuitry is provided to detect presence of the second device on the link by detecting a pulldown voltage generated from termination of the second device on the link, and pulldown relay circuitry is provided to generate an emulated version of the pulldown voltage of the second device on pins to connect to the first device in response to detecting presence of the second device on the link.

    Abstract: Systems and methods may provide for an optical module including an optical demultiplexer to receive a wavelength division multiplexed (WDM) signal from a single receive optical fiber and separate the WDM signal into a plurality of optical signals. Additionally, the optical module may include a receiver conversion unit to convert the plurality of optical signals into a corresponding plurality of electrical signals. In addition, the optical module may include a buffer chip having a single clock and data recovery (CDR) module to recover a clock from a designated signal in the plurality of electrical signals and distribute the recovered clock to a plurality of data lanes corresponding to the plurality of electrical signals.

    Abstract: In one embodiment, an apparatus includes a processor, a laser, and a modulator. The processor is to generate a first electrical signal including first data and a second electrical signal including second data. The laser is to generate a multiplexed carrier signal comprising a first carrier signal and a second carrier signal, the laser to operate at a first laser power setting. The modulator is to generate a multiplexed optical signal including a first optical signal based in part on the first electrical signal and the first carrier signal and a second optical signal based in part on the second electrical signal and the second carrier signal. The apparatus is to transmit the multiplexed optical signal to a device and to retransmit the first data from the apparatus to the device based on a detection of error in a received version of the first data at the device. Other embodiments are described and claimed.
