Disclosed herein is a technique for a connection from an Ethernet physical transceiver (PHY) to an integrated connector module (ICM) where the connection and the ICM lack a common mode choke. The ICM can include a magnetic coupler that directly couples an Ethernet jack and the PHY.

Removal of common mode choke

Embodiments generally provide techniques for waking up a plurality of network devices from a power saving mode via layer 1 (L1) signaling. Embodiments include entering a power saving mode at a first network device, wherein logic for processing layer 2 and higher data is inactive during the power saving mode and receiving, while the first network device is in the power saving mode, a L1 bit stream from a second network device connected to the first network device. Additionally, embodiments include, upon determining that a predefined code is present within the received L1 bit stream, exiting the power saving mode at the first network device and transmitting a second L1 bit stream containing the predefined code to a third network device.

Enabling deep sleep and power saving through L1 signaling on stack interface

Techniques are provided for delivering power to powered devices. Power is received from an inline power device and the power is separated into multiple power distribution paths. The power is received at a connector jack comprising conductor pins configured to receive the power and data. A transceiver is configured to interface with the first portion and the second portion of the conductor pins of the connector jack. The power distribution paths are electrically isolated, and rectifying diodes are configured to interface with the conductor pins are also electrically isolated. The power is transmitted from the inline power device across the multiple power distribution paths.

Inline power device for multiple inline formats

Methods and apparatus for preventing unsupported links between a host device and a link partner over a network is disclosed. In one embodiment, a link control signal is employed to release the reset of the candidate PHY, place a candidate PHY of the host device in a boot state, determining whether the candidate PHY is fully functional, and release the candidate PHY to establish link with the link partner over the network.

An SFP module provides either a 1000Base-X or SGMII interface protocol to a host and provides a 1000Base-T media dependent interface (MDI). If the SFP module is coupled a host that only implements the 1000Base-X protocol then the SFP module translates the 1000Base-X protocol to the 1000Base-T protocol so that the host MAC sees the 1000Base-T SFP module as if it were an optical transceiver. If the host implements SGMII then the SFP performs auto-negotiation of speed and communicates with the host implement data transfer at a selected rate, e.g., 10, 100, or 1000 Mbps.
