Planar Optical Space Switch Architectures
Optical space switches are important subsystems in optical crossconnects (OXCs) and reconfigurable optical add/drop multiplexers (R-OADMs), while also having applications in more long-term communications scenarios, such as optical packet switching. This chapter develops the theory of operation of planar optical space switches, and illustrates the interrelationship that exists between device cha...
متن کاملAWG Based Optical Packet Switch Architecture
This paper discusses an optical packet switch (OPS) arch itecture, which utilizes the components like optical reflectors, tunable wavelength converters (TWCs), arrayed waveguide grating (AW G) and pieces of fiber to realize the switching action. This architecture uses routing pattern of AW G, and its symmetric nature, to simplify switch operation significantly. It is also shown that using multi...
متن کاملDynamically reconfigurable optical packet switch (DROPS).
A novel Dynamically Reconfigurable Optical Packet Switch (DROPS) that combines both spectral and spatial switching capabilities is proposed and experimentally demonstrated for the first time. Compared with an Arrayed Waveguide Grating Router (AWGR), the added spatial switching capability provided by the microelectromechanical systems (MEMS) enables dynamically reconfigurable routing that is not...
متن کاملThe “Staggering Switch”: An Electronically Controlled Optical Packet Switch
This paper presents an architecture and implementation issues of an “almost-all” optical packet switch that does not rely on recirculating loops for storage implementation. The architecture is based on two rearrangeably nonblocking stages interconnected by optical delay lines with different amounts of delay. We investigate the probability of loss and the switch latency as a function of link uti...
متن کاملThe “Packing” and the “Scheduling Packet” Switch Architectures for Almost All-Optical Lossless Networks
This paper proposes two almost all-optical packet switch architectures, called the “packing switch” and the “scheduling switch” architecture, which when combined with appropriate wait-for-reservation or tell-and-go connection and flow control protocols provide lossless communication for traffic that satisfies certain smoothness properties. Both switch architectures preserve the order of packets...
