Abstract:
1. An optical system employing an orthogonal frequency division multiplexing OFDM modulation, comprising: a transmitter using a decision processor to control first internal elements that can be operated in parallel and can be selectively powered off or hibernated; and a receiver using a processing decision element to control second internal elements that can be operated in parallel and can be selectively powered off or hibernated; wherein said control of said first and second internal elements enables tracking status of network traffic, adjustment of OFDM bandwidth based on a traffic decision and selectively powering off or hibernating parallel ones of said first and second internal elements; wherein said second internal elements comprise an interleaved lower-speed analog-to-digital-controller ADC with a track-and-hold capability to provide a high sampling rate, 1-1(2^n) analog-to-digital-controllers ADCs and corresponding track-and-hold capabilities to be powered off or hibernated when bandwidth is adjusted to 1/(2^n) of full bandwidth or below, where n is a selectable sampling rate factor.
