1. Flexible WSS accommodates advanced network architectures and modulation formats

Author

Frisken, Steve and Poole, Simon

Subjects
Network switches -- Usage, Computer networks -- Methods, Information networks -- Methods, Optical communications -- Methods, Network switch, Business, Telecommunications industry
Abstract

Thanks to technology advances, wavelength-selective switches now make economic as well as operational sense for a wider variety of applications, including higher-performance edge ROADMs., Reconfigurable optical add/ drop multiplexers (ROADMs) are now widely deployed in core network (metro and long-haul) applications, where wavelength-selective switches (WSS) have become established as the preferred wavelength switching fabric [...]

Modulation (Electronics) -- Methods, Optical communications -- Methods, Signal processing -- Methods, Wave propagation -- Methods, Digital signal processor, Business, Telecommunications industry
Abstract

OVERVIEW While modulation formats based on phase-shift keying have received a significant amount of attention, they may not be the most cost-effective approach for high-speed applications like 40 Gbps. One [...]
