Open Optical Communication Systems at a Hyperscale Operator

Journal of Optical Communications (2020)

Abstract

Open optical networks present a variety of benefits such as single vendor independence and the opportunity to select best in class devices for each individual role. In this paper we review two degrees of open optical networks, namely ones with transponder-line system and line system-line system interoperability. In this context we discuss Google's experiences with respect to optical link design, software, and controls, deployment, and operation.
