Abstract: A method of transmitting data may include receiving feedback information that includes effective channel bandwidths, signal-to-noise ratios (SNRs) associated with multiple optical channels on an optical link, and individual SNRs associated with subcarriers on each optical channel. The method may include determining multiple subcarrier power allocation schemes based on the feedback information. Each subcarrier power allocation scheme may be associated with a corresponding optical channel from the multiple optical channels and may be configured to allocate a signal power among subcarriers configured to transmit on the corresponding optical channel. The method may include determining, based on the feedback information, an optical power allocation scheme configured to allocate an optical power among the multiple optical channels. The method may include transmitting data on the multiple optical channels based on the multiple subcarrier power allocation schemes and the optical power allocation scheme.

Abstract: An example demultiplexer may include at least one dispersive element that is common to multiple wavelength channels. The demultiplexer may additionally include multiple field lenses positioned optically downstream from the at least one dispersive element, where a number of the field lenses is equal to a number of the wavelength channels. An example multiplexer may include a single piece power monitor assembly that includes a collimator lens array, a focusing lens array, and a slot integrally formed therein. The collimator lens array may be positioned to receive multiple wavelength channels from a laser array. The focusing lens array may be positioned to focus multiple portions of the wavelength channels onto an array of photodetectors. The slot may be configured to tap the portions from the wavelength channels collimated into the single piece power monitor assembly by the collimator lens array and to direct the portions toward the focusing lens array.
