Abstract:
1. An optical network, comprising: a first node having a first transceiver; a second node having a second transceiver; an optical working link extending between the first node and the second node; and an optical protection link extending between the first node and the second node; the first and second nodes being configured to exchange optical signals between the first and second nodes on the optical working link when the working link is operational and to exchange optical signals between the first and second nodes on the protection link if the working link fails; and the first and second transceivers being configured to perform electronic compensation for impairment of the exchanged optical signals based on a first set of electronic compensation parameters when the working link is operational and to perform electronic compensation for impairment of the exchanged optical signals based on a second set of electronic compensation parameters if the working link fails, the first and second sets of electronic compensation parameters being determined before the working link fails.
