Evolution to Colorless and Directionless ROADM Architectures

Broad deployment of ROADMs based on wavelength selective switching has significantly improved optical network flexibility. This paper discusses opportunities to extend upon these advances with colorless and directionless add/drop switching and indicates technology advancements toward this end.

A Temporally Interleaved Technique for Simultaneously Measuring Diagnostic Spectral Parameters and Link Performance in Active Optically Amplified Systems

We present a novel measurement technique for spectral measurements of optically amplified systems that enables simultaneous measurement and therefore correlation of a diagnostic parameter and the performance of the link.
