Rapid advances in optical technologies have been an impetus for deploying photonics in access, storage, backbone and grid networks, hence realizing the long standing quest for transporting data at multi-terabit rates. In particular, long-haul domains have seen significant induction of advanced dense wavelength-division multiplexing (DWDM) technology, while coarse WDM (CWDM) technologies have steadily permeated into the more focused metro/regional and edge domains. A complementary advance has been the development of next generation SONET/SDH grooming technologies. Standardization bodies, in particular IETF and ITU, are actively developing unified provisioning frameworks as well as flexible and intelligent control-plane architectures for optical and electronic layers. Challenges are today placed in understanding how to engineer both the backbone and the access section of the optical network. In the backbone time has come to provide efficient and reliable network design and operation that jointly exploits the latest optical transmission and electronic switching technologies. A multi-layer network design has been realized as a viable approach to optimize the available resources. Hence, traffic grooming will depart from a traditional implementation at the SONET/SDH level to a multi-layer approach. In addition, the IETF and ITU-T have started efforts to standardize virtual private networking (VPN) provisioning at layer 1 in backbone networks. There has also been growing interest in a centralized control plane that embeds integrated (optical and electronic) control and management policy and strategy, complemented by a distributed control plane that houses operational control.

In the access area a great interest resides in innovative solutions well beyond the upgrade of existing infrastructures. Significant interest is devoted to reliable and secure WDM passive optical network (PON) access architectures, pushing genuine fiber access all the way to the ultimate end-users, whether at home or at office.

Photonic technologies are increasingly considered for the implementation of high-performance packet switching architectures, such as Ethernet switches or IP routers, and also low-latency interconnections in large data centers. The possible applications of photonics in switching range from the implementation of optical switching fabrics, to high performance board-to-board and chip-to-chip interconnections. The use of photonics in switching boxes is demanding new, photonics friendly, design of switching architectures.
