Ultrafast optical technologies for large-capacity TDM/WDM photonic networks

Abstract

As the Internet data traffic increases explosively, the optical networks will evolve into "photonic networks", in which "wavelength" label is used to route largecapacity optical signals at optical path cross connect (OPXCs) nodes.[34] Further development of ultrafast all-optical processing technologies enables us to further upgrade the photonic networks into those with much more flexibility and higher transparency, where ultrafast optical signals of any bit rates (2.5, 10, 40, 100, 160 G/ch) and frame/modulation formats (GbE, 10 GbE, SDH, OTN/ NRZ, RZ, CS-RZ, RZ-DPSK, etc.) are processed and transmitted all-optically without optical-electrical-optical (O-E-O) conversion from end-to-end.
