Multi - channel Spectrum Analyzer for High Capacity Optical Transport Networks

Layered switch architectures for high-capacity optical transport networks

We propose and analyze layered switch architectures that possess high design flexibility, greatly reduced switch size, and high expandability. The improvement in loss and crosstalk due to the reduced switch size is also discussed. Theoretical models have been developed to compute the network blocking probability using these architectures. Low blocking probability and high network utilization ar...

Ultra-High Capacity Optical Transmission Technologies for 100 Tbit/s Optical Transport Networks

This paper describes ultra-high capacity wavelengthdivision multiplexed (WDM) transmission technologies for 100-Tbit/sclass optical transport networks (OTNs). First, we review recent advances in ultra-high capacity transmission technologies focusing on spectrallyefficient multi-level modulation techniques and ultra-wideband optical amplification techniques. Next, we describe an ultra-high capac...
