Claim:
1. A method of transmitting data through an optical link, the method comprising: receiving feedback information that includes effective channel bandwidths, signal-to-noise ratios (SNRs) associated with multiple optical channels on the optical link, and individual SNRs associated with subcarriers on each optical channel; determining multiple subcarrier power allocation schemes based on the feedback information, wherein each subcarrier power allocation scheme is associated with a corresponding optical channel from the multiple optical channels and is configured to allocate a signal power among subcarriers configured to transmit on the corresponding optical channel; determining, based on the feedback information, an optical power allocation scheme configured to allocate an optical power among the multiple optical channels; and transmitting data on the multiple optical channels based on the multiple subcarrier power allocation schemes and the optical power allocation scheme.
