We propose a novel control algorithm for Grouped Routing networks that utilize a metric for residual capacity estimation. Numerical experiments under growing traffic scenarios confirm that it can maximize the fiber frequency utilization.
A novel resilient optical routing network architecture that adopts finely granular protection and finely granular add/drop is presented. The routing scheme defines optical pipes such that multiple optical paths can be carried by each pipe and can be dropped or added at any node on the route of a pipe. The routing scheme also makes it possible to enhance frequency utilization within pipes as we recently...
We propose a novel tunable-filter configuration for optical C/D/C drop in ROADMs, which achieves low insertion loss and low power consumption. A prototype is monolithically fabricated with PLC technologies and its good filtering performance is experimentally confirmed by BER measurement.
We propose a novel compact wavelength tunable filter that combines multi-input/output AWG wavelength routing and switches. The necessary switch scale is shown to be significantly reduced. The wavelength selection capability of a prototype is confirmed.
