Abstract: An authentication method, network switch, and network device are provided. In one example, a method is described that includes receiving a first signal indicative of a data lane being activated and configured to carry data to or within the network switch, receiving a second signal indicative of an authentication lane being established in the network switch or a device connected to the network switch, where the authentication lane is different from the data lane, and enabling data transmission across the data lane only in response to receiving the second signal indicative of the authentication lane being established.

Abstract: Embodiments are disclosed for a coupling element with embedded modal filtering for a laser and/or a photodiode. An example system includes a laser and an optical coupling element. The laser is configured to emit an optical signal. The optical coupling element is configured to receive the optical signal emitted by the laser. The optical coupling element is also configured to be connected to an optical fiber such that, in operation, the optical signal is transmitted from the laser to the optical fiber via the optical coupling element. Furthermore, the coupling element comprises a tapered section that provides modal filtering of the optical signal.

Abstract: An printed circuit board (PCB) assembly and method of assembling the same for a high-speed, short-reach communication link are described that provide a mechanism for transmitting radio frequency (RF) waves from one digital electronic component of the PCB assembly to another, where the second digital electronic component is located either on the same PCB assembly or on a second PCB assembly. The assembly includes a PCB having multiple layers and a digital electronic component supported by the PCB. At least one of the layers defines a channel that confines RF waves therein. An RF antenna in communication with the digital electronic component extends into the channel, and the RF antenna transmits RF signals generated by the digital electronic component into the channel as RF waves or receives RF waves via the channel and conveys corresponding RF signals to the digital electronic component.

Abstract: An opto-mechanical coupler and corresponding method of manufacture are provided. The coupler may include a body defining a bottom surface, a receiving surface, and a reflective surface. The reflective surface may redirect optical signals between a first direction and a second direction. The receiving surface may position one or more optical fibers along the second direction such that an optical signal from the plurality of optoelectronic transceivers may be directed into the one or more optical fibers or an optical signal received from the one or more optical fibers may be directed into the plurality of the optoelectronic transceivers. The receiving surface may also define grooves to locate each optical fiber at a height relative to a first optical path in the second direction.
