    Abstract: Processes and apparatuses described herein provide for an efficient cyclical fiber-optic connection between a source component and multiple destination components in a computing environment. A comb laser generates a laser signal that includes laser light of a first frequency that is red-shifted from a carrier frequency. The comb laser concurrently transmits the laser signal to four ring resonators via an optical waveguide. Three of the ring resonators are initially configured for optical resonance at a second frequency that is blue-shifted from the carrier frequency, while one of the ring resonators is initially configured for optical resonance at the first frequency. The laser signal is modulated to communicate data to a first target location associated with the ring resonator that is initially configured for optical resonance at the first frequency.

    Abstract: Examples herein relate to optical systems. In particular, implementations herein relate to an optical system including a bidirectional optical link such as an optical fiber. The optical system includes first and second optical modules coupled to opposing ends of the optical fiber. The first optical module is configured to transmit optical signals across the optical fiber in a first direction and the second optical module is configured to transmit optical signals across the optical fiber in a second direction opposite the first direction. Each of the first and second optical modules includes a multi-wavelength optical source configured to emit light. Respective channel spacing of the multi-wavelength optical sources of the first and second optical modules are offset from each other such that the respective wavelengths of the emitted light transmitted across the optical fiber from the first and second optical sources do not overlap.

    Abstract: Example implementations relate to executing a workload in a computing system including processing devices, memory devices, and a circuit switch. An example includes identifying first and second instruction-level portions to be consecutively executed by the computing system; determining a first subset of processing devices and a first subset of memory devices to be used to execute the first instruction-level portion; controlling the circuit switch to interconnect the first subset of processing devices and the first subset of memory devices during execution of the first instruction-level portion; determining a second subset of the processing devices and a second subset of the memory devices to be used to execute the second instruction-level portion; and controlling the circuit switch to interconnect the second subset of processing devices and the second subset of memory devices during execution of the second instruction-level portion.

    Abstract: An optical network includes top networking ports coupled to a packet switch, first media converters, second media converters, and bottom networking ports. The first media converters are coupled to top networking ports, each of the first media converters including a first ASIC transceiver that has a circuit switch function. The second media converters are coupled to the first media converter via optical cables to receive the optical signals. Each of the second media converters includes a second ASIC transceiver that has a circuit switch function. The bottom networking ports are coupled to the second media converters. The first ASIC transceiver and the second ASIC transceiver are configured to transmit a signal from one of the top networking ports to any one of the bottom networking ports, and transmit a signal from one of the bottom networking ports to any one of the top networking ports.

    Abstract: An optical transceiver module includes an optical transceiver and a controller. The optical transceiver has a ring filter configured to transmit optical signals from or receive optical signals for the optical transceiver module. The controller is configured to: detect a carrier frequency at the optical transceiver; detect a data signal frequency of data at the optical transceiver; determine a bit error rate of the data; and in response to determining that the bit error rate of the data is greater than a threshold, periodically vary a central wavelength of the ring filter at a frequency at least three orders slower than the data signal frequency.

    Abstract: The present disclosure provides an effective solution to employ hyperscale photonics connectivity using existing server connections. The solution described in the present disclosure eliminates top-of-rack switches and facilitates a manner for servers to connect directly to middle-of-row switches. An apparatus consistent with the present disclosure includes a primary transceiver device. The primary server-end transceiver device comprising a photonics transceiver and a first electrical transmitter. The apparatus further includes a first secondary server-end transceiver device, the first secondary server-end transceiver device comprising a second electrical transmitter. In addition, a first electrical cable electrically couples the primary server-end transceiver to the first secondary server-end transceiver device. The present disclosure enables the use of an input fiber connection and a photonics transceiver to effect two sets of electrical connections on different servers.
