A gigabits zero-delay arrangement for enabling continuous monitoring of data traversing through a network in a high-speed Ethernet environment is provided. The arrangement includes a high-speed network device configured for monitoring the data flowing through the network. The arrangement also includes a primary power source for providing a first power to circuitry of the gigabits zero-delay arrangement. The arrangement further includes a sensor controller configured for monitoring power flowing into the high-speed network device and for establishing an alternative communication link.
