AWG 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 کاملModular AWG-based Optical Shuffle Network
This paper proposes an arrayed-waveguide grating (AWG) based wavelength-divisionmultiplexing (WDM) shuffle network. Compared with previous optical shuffle networks, our proposal is compact, easy to implement, highly scalable, and cost effective. OCIS codes: (060.4258) Networks, network topology; (060.4265) Networks, wavelength routing
متن کاملA Novel Packet Switch Node Architecture for Contention Resolution in Synchronous Optical Packet Switched Networks
Packet contention is a key issue in optical packet switch (OPS) networks and finds a viable solution by including optical buffering techniques incorporating fiber delay lines (FDLs) in the switch architecture. The present paper proposes a novel switch architecture for packet contention resolution in synchronous OPS network employing the packet circulation in FDLs in a synchronized manner. A mat...
متن کاملAn Optical Packet Switch based on Parametric Wavelength Converters
In an OPS, an optical fiber carries several wavelengths to transmit packets. An input fiber may carry as many packets as wavelengths that could be destined to one or several output fibers. The output contention occurs when multiple packets from different input fibers are destined to a single output fiber using the same wavelength at the same time. Only one packet is forwarded to the output fibe...
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...
