In one embodiment, an apparatus includes an enclosure configured for connection to a printed circuit board, a substrate within the enclosure, a plurality of components mounted on the substrate, a fluid inlet connector, a fluid outlet connector, and a plurality of flow channels within the enclosure, at least one of the components disposed in each the flow channels and segregated from other components in another of the flow channels. The enclosure is configured for immersion cooling of the components.

Optical signal to noise ratios that more accurately characterize optical link noise are determined. As noise induced by an optical receiver does not generally vary with an input optical signal power, a power of an incoming optical signal is varied at the receiver. A resulting variation in noise measure represents a variation in link noise and does not include any variation caused by receiver noise, as receiver noise does not generally vary with optical signal power. Thus, the contribution of optical link noise can be discerned from other noise induced by the receiver itself. A more accurate characterization of optical link performance is thus provided.

In one embodiment, an apparatus includes a substrate comprising a first surface and a second surface opposite to the first surface, an integrated circuit attached to the first surface of the substrate, and a cold plate attached to the second surface of the substrate with an electrical path extending through the cold plate for transmitting power from a power component connected to the cold plate, to the integrated circuit.

An example method for managing time offset and frequency drift in asynchronous Data Over Cable Service Interface Specification (DOCSIS) Remote Physical layer (R-PHY) network environments is provided and includes receiving, at a first hardware device, time synchronization message from a remote second hardware device in the DOCSIS R-PHY network, determining a time difference between a first clock at the first hardware device and a second clock at the second hardware device from the time synchronization message; and re-stamping an event message based on the time difference.
