  • Publication number: 20240121158
    Abstract: Apparatuses, systems, and methods are provided for scalable networking systems. An example system includes a plurality of core switches and a first stage patch panel associated with operation of a first set of network ports. In an operational configuration in which the first stage patch panel is coupled with the plurality of core switches, the first stage patch panel is configured to operatively couple the first set of network ports and a first portion of the plurality of core switches such that signals may pass therebetween. Furthermore, the first stage patch panel may preclude communication to a remaining portion of the plurality of core switches. The system may include a second stage patch panel associated with a second set of network ports that is operatively coupled with the plurality of core switches in the absence of the first stage patch panel so as to scale the networking system.

  • Publication number: 20240039627
    Abstract: Systems, computer program products, and methods are described herein for network discovery, port identification, and/or identifying fiber link failures in an optical network, in accordance with an embodiment of the invention. The present invention may be configured to sequentially connect each port of an optical switch to a network port of a server and generate, based on information associated with network devices connected to the ports, a network map. The network map may identify which network devices are connected to which ports of the optical switch and may permit dynamic port mapping for network installation, upgrades, repairs, and/or the like. The present invention may also be configured to determine a fiber link in which a failure occurred and reconfigure the optical switch to allow communication between an optical time-domain reflectometer and the fiber link to test the fiber link.

  • Publication number: 20230412265
    Abstract: A transceiver module for providing operational resilience is presented. The transceiver module is configured to receive first data via a first optical module in a first configuration of operation and detect, using an adapter that is operationally connected to the first optical module, an operational failure of the first optical module. In response to detecting the operational failure, the transceiver module is configured to switch, via the adapter, from the first configuration of operation to a second configuration of operation by: automatically engaging a second optical module; triggering the first data that was initially directed into a first input port of the first optical module to be directed into a second input port of the second optical module; and receiving the first data from a second output port of the second optical module.

  • Patent number: 11791902
    Abstract: A photonics frequency comb generator includes two integrated dies: an indium phosphide die laser of a first wavelength is grown on from, and a silicon photonics die having a microring resonator connected to the laser and frequency modulators. The microring resonator converts the first wavelength into a number of second wavelengths. One type of the microring resonator is a hybrid non-linear optical wavelength generator, comprising non-silicon materials, such as SiC or SiGe built on silicon to yield a non-linear wavelength generation. The second wavelengths are generated by adjusting the ring's geometric size and a distance between the ring and the traverse waveguide. Another type of microring resonator splits the first wavelength into a plurality of second wavelengths and transmits the multiple second wavelengths to filters and modulators, and each selects and modulates one of the second wavelengths in a one-to-one relationship.
