Design of Reconfigurable Optical Add and Drop Multiplexer(ROADM) using Optisystem

Abstract

As bandwidth consumption continues to explode in a challenging economic environment, service providers and enterprises need to maximize their network’s efficiency – deliver more with less. Effective use of Reconfigurable Optical Add Drop Multiplexers (ROADMs) is key to this strategy. Increasing the flexibility, scalability and remote configurability of a network lowers Operational Expenses (OPEX). Using ROADMs, a bandwidth provider can quickly turn up new services, alter networks as needed, protect his revenue stream and reduce truck rolls through remote management. However, the ROADM landscape is large and diverse, and all the available technologies and architectures can at times be confusing and potentially prevent operators from maximizing their networks’ potential. Optical multiplexing is the key function of a WDM network and reliable method for data transport networks. WDM networks configured as rings/mesh along with Optical Add-Drop Multiplexers supports added flexibility, simplicity and augment the spectral efficiency. Further enhancement achieved with Reconfigurable OADM architectures, growing briskly along with automatic network management, let the transport network to acclimatize with dynamically varying environment and flexibly respond to the transport network changes. It permits single or many wavelengths to be added and/or dropped from a transport fiber without optical-to-electrical-to-optical domain translation. Presently ROADM technology has revolutionized optical networking and an inseparable part of modern optical communication offering huge bandwidth for data transport at minimum expense. In this view the article presents comprehensive study for numerous generations of ROADM and their architecture and persistent development.
