Optical fibers allow for low-loss transmission of extremely high bandwidths over long distances. Therefore, optical fibers nowadays provide almost all data connectivity, for example in trans-oceanic cables, within and between data centers, between 5G cell towers and in fiber to the home. Consequently, novel techniques to sustain this growth in the decades to come are required.
To support traffic growth, future optical transmission systems will have to transmit orders of magnitude more data and at the same time enable the transition towards energy efficiency green networks. Modern trans-oceanic fiber-optical cables can transmit 10s of Terabits per second per fiber pair. These data rates are enabled by extensive parallelization through multiplexing of physical dimensions.

Signal Processing and Sound Quality
Tech Topic | February 2022 Hearing Review
By Laura Winther Balling, PhD, Lars Dalskov Mosgaard, PhD, and Dana Helmink, AuD
Hearing aid signal processing is central to the sound that surrounds the user every day. This article lays out different possible signal-processing strategies, focusing on the choice of filter bank and sampling rate, and how these relate to sound quality. Although both time- and frequency-domain filter banks have their advantages, the sound-quality benefits of a time-domain filter bank outweigh other considerations.
