  • Channelized transmission over openZR-extended optical network
    Patent number: 11722271
    Abstract: According to an aspect of an embodiment, operations may include receiving a first Ethernet signal having a first data rate less than a second data rate, the second data rate being a ZR data rate. The operations may also include dividing the first Ethernet signal into a plurality of first-signal sub-signals that each have a third data rate that is less than the first data rate. Moreover, the operations may include generating a second Ethernet signal having the second data rate, the generating of the second Ethernet signal being based on the plurality of first-signal sub-signals such that the second Ethernet signal includes the plurality of first-signal sub-signals. Further, the operations may include providing the second Ethernet signal to a ZR network such that the second Ethernet signal is a ZR signal.

  • Method and system for protection switching
    Patent number: 8335428
    Abstract: A method is provided for protection switching in an optical network. The method may include establishing a baseline power level for a channel. The method may further include receiving a signal associated with the channel via each of a first path of the optical network and a second path of the optical network. The method may also include monitoring a power intensity of the signal received via the first path. The method may additionally include protection switching from the signal received via the first path to the signal received via the second path in response to a determination that the baseline power level exceeds the power intensity of the signal received via the first path by a predetermined threshold.
