Optical networking has emerged as the foundation for campus, metro and wide-area networking with the ability to integrate voice, video, data and storage over a single network.

Multiservice networking
Synchronous Optical Networking/Synchronous Digital Hierarchy (SONET/SDH) provides increased bandwidth and performance while facilitating data center, application server, storage and network infrastructure consolidation to optimize resources and reduce costs. In addition, optical networking supports storage-area networking (SAN) and IP-based network-attached storage (NAS) solutions to effectively access, manage, and protect corporate data, and to provide the foundation for business resilience applications.
