The prevalent network node architecture in the optical transport networks is the
Reconfigurable Optical Add/Drop Multiplexer (ROADM). High-degree ROADM architectures …

Reconfigurable Optical Add/Drop Multiplexers, ROADMs, are key enablers of the modern
optical communication services to support the remote provisioning of the optical paths and …

This paper proposes a multicasting and fault-tolerant optical crossconnect (MFOXC)
architecture that can support multicasting and fault tolerance. First, a tap-based and two …

A fault‐tolerant high‐performance SElf‐Routing 2× 2 Optical ATM Switch (SEROS) is
proposed. The switch is designed using all‐optical components which allows the …

This paper reviews the dependencies between the node-level architecture, the wavelength
selective switches, the multiplexer/demultiplexers, and the transceivers within advanced …

This thesis is about reconfigurable and transparent wavelength division multiplexed (WDM)
networks. Reconfigurability is used to achieve higher surveillance and throughput in the …

A periodic add/drop system in a fiber ring network was investigated using a reconfigurable
optical add/drop multiplexer (ROADM) in a re-circulating fiber loop. After seven cascaded …

With the unprecedented increase of internet and broadband services, communication
industries are requiring new solutions to reduce network complexity and to provide low cost …

The Passive Optical Network (PON) was proposed as a solution for the bandwidth
bottleneck at the Access Networks, mainly due to the characteristics of the fibers. A failure in …

Optical networks, based on the emergence of the optical layer in transport networks, provide
higher capacity and reduced costs for new network applications such as the VoIP, video on …
