<P>PROBLEM TO BE SOLVED: To compensate for optical dispersion in an optical signal in an optical network. <P>SOLUTION: The method for compensating for the optical dispersion includes a step of receiving the optical signal at a first node of the optical network that includes a first set of channels and a second set of channels that are received using coherent digital receivers at a second node of the optical network. Each coherent digital receiver provides electronic dispersion compensation for the received channel at the second node. The method also includes a step of forwarding the first set of channels from the first node without performing optical dispersion compensation on those channels. Furthermore, the method includes a step of compensating for optical dispersion in the second set of channels at the first optical node and forwarding those channels from the first node. <P>COPYRIGHT: (C)2011,JPO&INPIT |
