  • Testing transceiver ports of a network device with on-chip time domain reflectometry diagnostic tests
    Patent number: 12603826
    Abstract: A network device may identify an integrated circuit, a port group number, port lanes, and port channels associated with a transceiver port of a network device, and may map the integrated circuit, the port group number, the port lanes, and the port channels to the transceiver port. The network device may provide a time domain reflectometry pulse to a channel of the transceiver port at a first time and with a first voltage, and may receive a reflected time domain reflectometry pulse via the channel at a second time and with a second voltage. The network device may calculate a distance and an impedance of the channel based on the first time, the second time, the first voltage, and the second voltage, and may determine a status of the channel based on the distance and the impedance. The network device may output the status of the first channel.
