Implementation Aspects of Coherent Transmit and Receive Functions in Application-Specific Integrated Circuits

Andreas Leven and Laurent Schmalen,    Bell Labs, Alcatel-Lucent, Lorenzstr. 10 70435 Stuttgart, Germany

In this chapter, we will discuss implementation aspects of current and future application-specific integrated circuits (ASICs) for coherent optical transmission systems. Main building blocks for such ASICs are data converters, baseband signal processing, forward error correction and interfacing. We will highlight selected implementation details.

15.1 Introduction

Coherent line cards are seen as key enablers for high-speed optical communication systems. Today, more than 80% of all shipped 100 G line cards are based on coherent ...
