摘要： An apparatus includes an array of electro-optical transducers, control circuitry, and a connector housing. The electro-optical transducers are configured to convert between electrical signals and respective optical signals conveyed over respective optical fibers. The control circuitry is configured, in response to a failure of a first electro-optical transducer in the array that is associated with a given optical fiber, to switch one or more of the electrical signals and the optical signals so as to replace the first electro-optical transducer with a second electro-optical transducer in the array in conveying an optical signal over the given optical fiber. The connector housing contains the array of the electro-optical transducers and the control circuitry.

摘要： Embodiments are disclosed for a quantum key distribution enabled intra-datacenter network. An example system includes a first vertical cavity surface emitting laser (VCSEL), a second VCSEL and a network interface controller. The first VCSEL is configured to emit a first optical signal associated with data. The second VCSEL is configured to emit a second optical signal associated with quantum key distribution (QKD). Furthermore, the network interface controller is configured to manage transmission of the first optical signal associated with the first VCSEL and the second optical signal associated with the second VCSEL via an optical communication channel coupled to a network interface module.

摘要： An apparatus includes a bank of optical detectors, an input optical filter and a selector. The optical detectors are configured to output respective detection indications in response to detecting a presence of an optical signal. The input optical filter is configured to receive an input optical signal having an input wavelength, and to route the input optical signal to one of the optical detectors in the bank depending on the input wavelength. The selector is configured to select an output wavelength based on the detection indications of the optical detectors, and to cause generation and transmission of an output optical signal at the selected output wavelength.

摘要： Optical communication modules and associated methods and computer program products for performing network communication security are provided. An example optical module includes a substrate, a first optoelectronic component supported by the substrate configured for operation with optical signals having a first wavelength, and a second optoelectronic component supported by the substrate configured for operation with optical signals having a second wavelength. The module further includes an optical communication medium defining a first end in optical communication with the first optoelectronic component and the second optoelectronic component and a second end. The module also includes security circuitry operably connected with the first optoelectronic component and the second optoelectronic component. The security circuitry determines the presence of a noncompliant component coupled with the optical communication medium at the second end based upon operation of the second optoelectronic component.

摘要： An electro-optical link is provided. In an example embodiment, the electro-optical link includes a number of vertical cavity surface emitting lasers (VCSELs); one or more drivers that operate the VCSELs such that each of the VCSELs selectively emits an optical signal; one or more multiplexers that multiplex a number of optical signals into an optical fiber, each optical signal emitted by one of the VCSELs; and one or more optical fibers. At least two optical signals are multiplexed into each optical fiber of the one or more optical fibers. In some example configurations eight or sixteen optical signals are multiplexed into one optical fiber.
