The authors studied how using two-way communication (bidirectional transmission) in parts of special internet cables called Hollow-Core Fibers (HCF) can improve network performance. They found that upgrading just half of the network links to bidirectional HCF increases data speed by at least 40% compared to traditional one-way fiber cables. This partial upgrade also achieves 85% of the energy savings possible from fully upgrading the entire network to unidirectional HCF. Their work shows benefits of a selective upgrade approach rather than a complete overhaul.

Abstract
We investigate selectively deploying bidirectional transmission in hybrid Hollow-Core Fiber (HCF) networks. Upgrading 50% of links to bidirectional HCF yields at least a 40% throughput increase compared to unidirectional SMF and captures 85% of the power consumption reduction of a full unidirectional HCF network upgrade.
